de Azevedo, Orlando D. C. C. published the artcileSynthesis and Photochromism of Novel Pyridyl-Substituted Naphthopyrans, Application In Synthesis of 151-10-0, the main research area is pyridyl naphthopyran synthesis photochromism; safety diazonium salt.

Multitarget synthetic strategies to access novel photochromic 3H-naphtho[2,1-b]pyrans decorated with pyridyl units are described. The new pyridyl-substituted 3H-naphtho[2,1-b]pyrans display good photochromic properties with reversible generation of photomerocyanines, which exhibit mainly orange/red hues. Photochromic parameters including photocolorability and persistence of color vary tremendously on structural modification of the naphthopyran core. Safety: diazonium salts should be kept damp with water at all times.

A practical method for the umpolung selenocyanation of aryl ketones, alkyl ketones, β-ketoesters and electron-rich arenes was developed, afforded various selenocyanates in moderate to excellent yields. This transformation proceeded by an oxidative umpolung selenocyanation through nitrogen oxides-mediated electrophilic selenocyanation process. This method is simpler, more efficient, and less costly than precedent methods. Further transformations of the arylselenocyanate was performed to prove the synthetic utility of this methodol.

Song, Song published the artcileDMSO-catalysed late-stage chlorination of (hetero)arenes, Safety of 1,3-Dimethoxybenzene, the main research area is arene heteroarene chlorination dimethyl sulfoxide catalyst.

A highly efficient aromatic chlorination of arenes such as 1-methyl-indazole, imidazo[1,2-a]pyrazine, phenylthiophene, anthracene, etc. that is catalyzed by DMSO with N-chlorosuccinimide as the chloro source is reported. The mild conditions, easy-availability and stability of the catalyst and reagents, as well as good functional-group tolerance, showed the approach to be a versatile protocol for the late-stage aromatic chlorination of complex natural products, e.g., papaverine, drugs, e.g., diclofenac and peptides, e.g., I. The multi-gram experiment and low-cost of N-chlorosuccinimide and DMSO show great potential for drug discovery and development in industrial applications.

Holmberg-Douglas, Natalie published the artcileArene Cyanation via Cation-Radical Accelerated-Nucleophilic Aromatic Substitution, Recommanded Product: 1,3-Dimethoxybenzene, the main research area is aryl nitrile chemoselective preparation; acridinium catalyst photochem nucleophilic aromatic substitution aryl alkyl ether; chemoselective photochem cyanation aryl alkyl ether acetone cyanohydrin; calculation atomic charge radical cation regioselectivity photochem cyanation.

In the presence of a highly oxidizing acridinium tetrafluoroborate, aryl Me ethers and an aryl benzyl ether underwent chemoselective nucleophilic aromatic substitution reactions with cyanide generated in situ from acetone cyanohydrin and NaHCO3 in 1,2-dichloroethane/2,2,2-trifluoroethanol to yield aryl nitriles. The observed selectivities for nucleophilic aromatic substitution over direct cyanation correlated with the sites with the largest increases in pos. charge between the ethers and their radical cations; the transition state structures and activation barriers for cyanation of veratrole and Me 3,4-dimethoxybenzoate and cyanation kinetics and lack of linear free energy relationships were determined

Wang, Baolu published the artcileA Borane Lewis Acid in the Secondary Coordination Sphere of a Ni(II) Imido Imparts Distinct C-H Activation Selectivity, Name: 1,3-Dimethoxybenzene, the main research area is aromatic compound carbon hydrogen bond activation kinetics nickel imide; crystal structure boryldiphosphine nickel imido metallacyclic complex.

Two borane-functionalized bidentate phosphine ligands that vary in tether length were prepared to examine cooperative metal-substrate interactions. Ni(0) complexes react with aryl azides at low temperatures to form structurally unusual κ2-(N,N)-N3Ar adducts. Warming these adducts affords products of N2 extrusion and in one case, a Ni-imido compound that is capped by the appended borane. Reactions with 1-azidoadamantane (AdN3) provide a distinct outcome, where a proposed Ni imido intermediate activates the sp2 C-H bonds of arenes, even in the presence of benzylic C-H sites. Combined exptl. and computational mechanistic studies demonstrate that the unique reactivity is a consequence of Lewis-acid-induced polarization of the Ni-NR bond, potentially providing a synthetic strategy for chemoselective reaction engineering.

Vodnala, Nagaraju published the artcileLewis Acid-Promoted Typical Friedel-Crafts Reactions Using DMSO as a Carbon Source, Safety of 1,3-Dimethoxybenzene, the main research area is diarylmethane preparation; arene dimethyl sulfoxide Friedel Craft reaction Lewis acid catalyst.

A mild and efficient synthetic protocol for the synthesis of sym. and unsym. diarylmethanes (DAMs) R1CH2R2 (R1 = 4-methoxyphenyl, 2,4,6-trimethylphenyl, 1H-indol-3-yl, 4-hydroxy-2-oxo-2H-chromen-3-yl, etc.; R2 = 4-hydroxy-3,5-dimethylphenyl, 5-methylfuran-2-yl, 4-amino-3,5-bis(propan-2-yl)phenyl, etc.) was reported. Using DMSO as the C1 source and TMSOTf as the Lewis acid promoter, a series of functionalized sym. and unsym. DAMs was synthesized in high yields. Gratifyingly, DMSO plays a dual role as a solvent and a C1 source and can also be replaced with its deuterated counterpart, DMSO-d6, enabling the incorporation of the -CD2 moiety into the diarylmethane skeleton. The developed approach has been applied to a wide range of substrates having various functional groups, and this protocol has also been extended to the synthesis of an anti-breast cancer agent and an anticoagulant agent using common feedstock compounds In addition, the postulated mechanism has been explicitly demonstrated via control experiments

Karmel, Caleb published the artcileMechanism of the Iridium-Catalyzed Silylation of Aromatic C-H Bonds, Category: isoquinoline, the main research area is arene silylation mechanism iridium catalysis.

Phenanthroline ligands and [Ir(cod)(OMe)]2 form complexes that catalyze the silylation of aromatic and aliphatic C-H bonds. However, no exptl. data on the identity of complexes related to the mechanism of this process or the mechanisms by which they react to functionalize C-H bonds have been reported. Herein, we describe our studies on the mechanism of the iridium-catalyzed silylation of aryl C-H bonds. The resting state of the catalyst is an iridium disilyl hydride complex (phenanthroline)Ir(SiMe(OTMS)2)2(H)(L), in which L varies with the arene and additives. An iridium disilyl hydride complex was isolated, characterized, and allowed to react with arenes to form aryl silanes. The kinetics of the reactions of electron-rich and electron-poor arenes showed that the rate-limiting step varies with the electronic properties of the arene. Computational studies on related iridium silyl complexes revealed that the high activity of iridium complexes with sterically encumbered phenanthroline ligands is due to a change in the number of silyl groups bound to iridium between the resting state of the catalyst containing the hindered phenanthroline and that containing less hindered phenanthroline.
