The palladium-catalyzed reaction of aryl halides and allylic alcs. was an attractive method for obtaining α,β-unsaturated aldehydes and ketones, which represent key intermediates in organic synthesis. In this context, a 1,2,3-triazol-5-ylidene (aNHC)-based palladium(II) complex formed in situ was found to be a selective catalyst for the syntheses of building blocks from the corresponding aryl halides and allylic alcs., with yields ranging from 50% to 90%. The lack of toxic effects of the ligand precursor (1,2,3-triazolium salt) of the palladium(II) complex for the harpacticoid copepod Amphiascoides atopus allowed to contrast the efficiency of the catalytic system with the potential impact of the principal waste chem. in global aquatic ecosystems, which has not been previously addressed.

Chen, Xuan;Zard, Samir Z. research published 《 Convergent Route to β-Amino Acids and to β-Heteroarylethylamines: An Unexpected Vinylation Reaction》, the research content is summarized as follows. Various protected β²-amino acids can be prepared by radical addition of β-phthalimido-α-xanthyl propionic acid, both as the free acid or as the Et ester. Successive radical additions provide access to more complex structures. In the case of the free acid, addition to certain heteroaromatics leads directly to β-heteroarylethylamines through spontaneous decarboxylation of the intermediate adduct. Forcing the decarboxylation in some cases generated a vinyl group by decarboxylative elimination of the phthalimido group.

Chen, Ya-Jing;Lei, Tao;Hu, Hui-Lan;Wu, Hao-Lin;Zhou, Shuai;Li, Xu-Bing;Chen, Bin;Tung, Chen-Ho;Wu, Li-Zhu research published 《 Tandem photoelectrochemical and photoredox catalysis for efficient and selective aryl halides functionalization by solar energy》, the research content is summarized as follows. Solar energy conversion is the most important chem. transformation for green and sustainable society. Represented herein is a coupled catalytic strategy for efficient, selective, and energy-saving organic transformations, i.e., a coupled photoelectrochem./photoredox setting with Sb₂(S,Se)₃ as a photocathode and N,N-bis(2,6-diisopropylphenyl)perylene-3,4,9,10-bis(dicarboximide) (PDI) as a photocatalyst shows full-solar-spectrum response extending visible and near-IR (Vis-NIR) light to 1,060 nm. At -0.84 V vs. SCE, the Vis-NIR photoexcited electron from Sb₂(S,Se)₃ reduces PDI to PDI·-. Then, the second photoexcitation by Vis light creates higher reducing PDI·-t (-1.86 V vs. SCE) for reduction of unactivated aryl halides. The resultant aryl radicals are applied for C-C, C-P, and C-B bond-forming reactions with excellent chemoselectivity and efficacy under external sacrificial agent-free conditions. This strategy not only utilizes full solar spectrum and surmounts the limited light absorption of photocatalysis, but also overcomes the high biased potential issue in electrocatalysis.

A selective phosphoranation of alkynes with phosphonium cation was developed, which directed a concise approach to isoquinolines from unactivated alkyne and nitrile feedstocks in a single step. Mechanistic studies suggested that the annulation reaction was initiated by the unprecedented phosphoranation of alkynes, thus representing a unique reaction pattern of phosphonium salts and distinguishing it from existing protocols that largely rely on the utilization of highly functionalized imines/oximes and/or highly polarized alkynes.

A highly Z-selective dienylation can now be achieved by a simple adjustment of a ligand, enabling stereodivergent synthesis of E- and Z-dienes RCH=CHCH=CH₂ (R = 4-cyanophenyl, 5-chloropyridin-3-yl, 2-methylpyrimidin-5-yl, etc.) from one reagent and in one step. A detailed mechanistic investigation of the E- and Z-selective dienylation provided insight into the divergent behavior of the two catalytic systems and revealed that differences in relative stabilities of catalytically active palladium phosphine complexes e.g., bis(1,2-bis(diphenylphosphino)benzene)palladium(0) have a major impact on the stereochem. outcomes of the dienylation.

De Tovar, Jonathan;Rataboul, Franck;Djakovitch, Laurent research published 《 From the grafting of NHC-based Pd(II) complexes onto TiO₂ to the in situ generation of Mott-Schottky heterojunctions: The boosting effect in the Suzuki-Miyaura reaction. Do the evolved Pd NPs act as reservoirs?》, the research content is summarized as follows. The assumption that the real active species involved in the Suzuki-Miyaura reaction are homogeneous, heterogeneous or both is often proposed. However a lack of characterization of the true catalytic entities and their monitoring makes assumptions somewhat elusive. Here, with the aim of getting new insights into the formation of active species in the Suzuki-Miyaura reaction, a family of palladium(II) complexes bearing bis(NHC) ligands was synthesized for immobilization at the surface of TiO₂. The studies reveal that once the complexes are anchored onto TiO₂, the mechanism governing the catalytic reaction is different from that observed for the non-anchored complexes. All complexes evolved to Pd NPs at the surface of TiO₂ under reaction conditions and released Pd species in the liquid phase. Also, this reactivity was boosted by the in situ generation of Mott-Schottky heterojunctions, opening new routes towards the design of heterogenized catalysts for their further implementation in reverse-flow reactors.

This catalyst was widely applicable in the hydrodehalogenation of halogenated aromatics with various functional groups (more than 40 examples), including the high concentration solution of aryl fluorides, polyhalogenated phenol, environmental pollutants like 2,4-dichlorophenoxyacetic acid (2,4-D) and triclosan. Furthermore, it could be easily recycled and reused, providing a green and cost-effective method for the degradation of polyhalogenated aromatic pollutants and synthesis of important structural units through hydrodehalogenation reactions.

The present work documents electrophilic substitution of azaarenes, mainly isoquinolines, with hypervalent iodine diazo reagents (HIDR) followed by formal [3+2]-dipolar cycloaddition in a tandem fashion. Other azaarenes viz. pyridines and phenanthridines too could be successfully used in the reaction. The methodol. capitalizes on the umpolung nature of α-aryliodonio diazo compounds for installing a nucleophile, i.e. azaarene, at their α-position. Subsequent ylide formation and intramol. 1,5-cyclization furnished 4,3-fused 1,2,4-triazolyl-azaarenes in good yields. The reaction is notable for its mild conditions, operational simplicity and fairly general scope.
