Optimizing Pt Electronic States through Formation of a Schottky Junction on Non-reducible Metal-Organic Frameworks for Enhanced Photocatalysis was written by Sun, Zi-Xuan;Sun, Kang;Gao, Ming-Liang;Metin, Onder;Jiang, Hai-Long. And the article was included in Angewandte Chemie, International Edition in 2022.SDS of cas: 52250-50-7 This article mentions the following:

Charge transfer between metal sites and supports is crucial for catalysis. Redox-inert supports are usually unfavorable due to their less electronic interaction with metal sites, which, we demonstrate, is not always correct. Herein, three metal-organic frameworks (MOFs) are chosen to mimic inert or active supports for Pt nanoparticles (NPs) and the photocatalysis is studied. Results demonstrate the formation of a Schottky junction between Pt and the MOFs, leading to the electron-donation effect of the MOFs. Under light irradiation, both the MOF electron-donation effect and Pt interband excitation dominate the Pt electron d. Compared with the “active” UiO-66 and MIL-125 supports, Pt NPs on the “inert” ZIF-8 exhibit higher electron d. due to the higher Schottky barrier, resulting in superior photocatalytic activity. This work optimizes metal catalysts with non-reducible supports, and promotes the understanding of the relationship between the metal-support interaction and photocatalysis. In the experiment, the researchers used many compounds, for example, 1-Phenyl-3,4-dihydroisoquinoline (cas: 52250-50-7SDS of cas: 52250-50-7).

1-Phenyl-3,4-dihydroisoquinoline (cas: 52250-50-7) belongs to isoquinoline derivatives. Quinoline and isoquinoline skeletons are among the most attractive frameworks with a wide range of biological and pharmacological activities. Lewis acid activation and nucleophilic attack can produce multiple regioisomers in quinolines and pyridines; isoquinolines generally only undergo attack at the 1-position.SDS of cas: 52250-50-7

Reactions of 1,2,3,4-tetrahydroisoquinoline derivatives with sulfur was written by Ajzert, K. Ilona;Takacs, Kalman. And the article was included in Liebigs Annalen der Chemie in 1987.Electric Literature of C15H13N This article mentions the following:

1,2,3,4-Tetrahydroisoquinolines react with sulfur in pyridine to give two different types of products, depending on the structure of the starting compounds 1-Substituted derivatives I [R = Me, Ph, CH₂CN, 3,4-(MeO)₂C₆H₃CH₂; R¹ = H, MeO; R² = R³ = H] undergo partial dehydrogenation with formation of, the corresponding 3,4-dihydroisoquinolines I [R, R¹ = same, R²R³ = bond]. 1,2,3,4-Tetrahydroisoquinolines I (R = R³ = H; R¹ = H, MeO; R² = H, Me, PhCH₂) bearing no substituent in 1-position yield the 3,4-dihydro-1(2H)-isoquinolinethiones I [RR³ = (:S), R¹, R² = same]. In the experiment, the researchers used many compounds, for example, 1-Phenyl-3,4-dihydroisoquinoline (cas: 52250-50-7Electric Literature of C15H13N).

1-Phenyl-3,4-dihydroisoquinoline (cas: 52250-50-7) belongs to isoquinoline derivatives. Being an analog of pyridine, isoquinoline is a weak base, with a pKa of 5.14. The discovery of chloroquine, the most well-known drug containing this stent, has helped bring about decades of malaria control and treatment.Electric Literature of C15H13N

Asymmetric Transfer Hydrogenation in Thermomorphic Microemulsions Based on Ionic Liquids was written by Hejazifar, Mahtab;Palvoelgyi, Adam Mark;Bitai, Jacqueline;Lanaridi, Olga;Bica-Schroeder, Katharina. And the article was included in Organic Process Research & Development in 2019.Electric Literature of C15H13N This article mentions the following:

A thermomorphic ionic-liquid-based microemulsion system was successfully applied for the Ru-catalyzed asym. transfer hydrogenation of ketones. On the basis of the temperature-dependent multiphase behavior of the targeted microemulsion, simple product separation as well as catalyst recycling could be realized. The use of water-soluble ligands improved the immobilization of the catalyst in the microemulsion phase and significantly decreased the catalyst leaching into the organic layer upon extraction of the product. Eventually, the optimized microemulsion system could be applied to a wide range of aromatic ketones that were reduced with good isolated yields (up to 98%) and enantioselectivities (up to 97%), while aliphatic ketones were less successful. In the experiment, the researchers used many compounds, for example, 1-Phenyl-3,4-dihydroisoquinoline (cas: 52250-50-7Electric Literature of C15H13N).

1-Phenyl-3,4-dihydroisoquinoline (cas: 52250-50-7) belongs to isoquinoline derivatives. Being an analog of pyridine, isoquinoline is a weak base, with a pKa of 5.14. Most traditional methods of generating isoquinoline do so via oxidative aromatization of dihydro- or tetrahydro-isoquinolines, usually offering some environmental or economic advantage.Electric Literature of C15H13N

Development of novel 1,2,3,4-tetrahydroisoquinoline derivatives and closely related compounds as potent and selective dopamine D₃ receptor ligands was written by Mach, Ulrich R.;Hackling, Anneke E.;Perachon, Sylvie;Ferry, Sandrine;Wermuth, Camille G.;Schwartz, Jean-Charles;Sokoloff, Pierre;Stark, Holger. And the article was included in ChemBioChem in 2004.SDS of cas: 52250-50-7 This article mentions the following:

Based on N-alkylated 1,2,3,4-tetrahydroisoquinoline derivatives which are structurally related to the partial agonist BP 897, a series of novel, selective dopamine D₃ receptor antagonists has been synthesized. Derivatization included changes in the arylamide moiety and the tetrahydroisoquinoline substructure leading to compounds with markedly improved selectivities and affinities in the low nanomolar concentration range. From the 55 structures presented here, (E)-3-(4-iodophenyl)-N-(4-(1,2,3,4-tetrahydroisoquinolin-2-yl)butyl)acrylamide (51) has high affinity (K_i(hD₃) = 12 nM) and a 123-fold preference for the D₃ receptor relative to the D₂ receptor subtype. Its pharmacol. profile offers the prospect of a novel radioligand as a tool for various dopamine D₃-receptor-related in vitro and in vivo investigations. In the experiment, the researchers used many compounds, for example, 1-Phenyl-3,4-dihydroisoquinoline (cas: 52250-50-7SDS of cas: 52250-50-7).

Disproportionation of dihydroisoquinolines was written by Brodrick, C. I.;Short, W. F.. And the article was included in Journal of the Chemical Society in 1949.Reference of 52250-50-7 This article mentions the following:

PhCH₂CH₂NHBz, cyclized by the method of Pictet and Kay (C.A. 3, 2434), gives 66% 1-phenyl-3,4-dihydroisoquinoline (I), b_1.2 146-9.5°. Distillation of 21.8 g. I at 340-5° and redistillation at 1.2-1.4 mm. (148-55°) gives 19.7 g. of a product which, crystallized from petr. ether, yields 14.1 g. of a mixture (II), m. 70-5°, and 3.3 g., m. 73-7°. II with picric acid gives the picrate of 1-phenylisoquinoline (III), m. 167-7.5°; with HCl in ether II yields the HCl salt, m. 227-9°, of 1-phenyl-1,2,3,4-tetrahydroisoquinoline (IV). II (5 g.) in 7 cc. CHCl₃ and 125 cc. petr. ether gives 1.03 g. IV. Adsorption of 1 g. of II in 150 cc. petr. ether on activated Al₂O₃ and elution with petr. ether give 0.28 g. III and 0.2 g. IV. II (5 g.) and 37.5 cc. Ac₂O, heated 3 hrs. at 100° and the product separated into basic and neutral fractions with HCl in ether, give 2.46 g. III and 2.5 g. of the 2-Ac derivative of IV, m. 91.5-2.5°. 1-Benzyl-3,4-dihydroisoquinoline (V) yields a HCl salt, with 0.5 mol. H₂O, m. 227-9°. Distillation of V at atm. pressure gives isoquinoline and a mixture b_0.7 145-8°, n_D²¹ 1.6252, with 0.33 atom of active H; 1-benzylisoquinoline was identified as the picrate and the HCl salt (with 2 mols. H₂O). Absorption maximum are given for these compounds in 0.1 N HCl and EtOH. In the experiment, the researchers used many compounds, for example, 1-Phenyl-3,4-dihydroisoquinoline (cas: 52250-50-7Reference of 52250-50-7).

1-Phenyl-3,4-dihydroisoquinoline (cas: 52250-50-7) belongs to isoquinoline derivatives. Although isoquinoline derivatives can be synthesized by several methods, relatively few direct methods deliver the unsubstituted isoquinoline. They are also used to make oil-soluble dyes, food colorants, pharmaceuticals, pH indicators and other organic compounds. Reference of 52250-50-7
