Frost, Grant B. published the artcileChemoselectivity for Alkene Cleavage by Palladium-Catalyzed Intramolecular Diazo Group Transfer from Azide to Alkene, Product Details of C7H6N2, the main research area is benzyl alkenyl phenyl carbamoyl azide preparation palladium catalyst chemoselective; benzo dihydroquinazolinone preparation; alkene cleavage; azides; cycloreversion; diazo group transfer; palladium.

A palladium-catalyzed intramol. azide to alkene DGT, which granted chemoselectivity over competing aziridination. The data supported a catalytic cycloreversion mechanism distinct from other known metal-catalyzed azide/alkene reactions: nitrenoid/metalloradical and (3+2) cycloadditions Kinetics experiments revealed an unusual mechanistic profile in which the catalyst was not operative during the rate-controlling step, rather, it was active during the product-determining step. Catalytic DGT was used to synthesize N-heterocyclic quinazolinones, a medicinally relevant structural core. On the competing aziridination and subsequent ring expansion to another N-heterocyclic core structure of interest, benzodiazepinones was also reported.

Zhu, Yiwen published the artcileCobalt-catalyzed carbonylative cyclization of N-(2-Vinylphenyl)picolinamides to access (NH)-quinolin-2(1H)-ones, Related Products of nitriles-buliding-blocks, the main research area is TFBen vinylphenyl picolinamide copper catalyst regioselective carbonylative cyclization; quinolinone preparation.

A cobalt-catalyzed carbonylative cyclization of N-(2-vinylphenyl)picolinamides for the construction of (NH)-quinolin-2(1H)-one scaffolds was developed. In this reaction, various free (NH)-quinolin-2(1H)-ones were produced in good yields (up to 92%) by employing benzene-1,3,5-triyl triformate (TFBen) as the CO source and picolinamide as the traceless directing group. Moreover, several synthetic transformations of the obtained (NH)-quinolin-2(1H)-ones were performed and a facile and rapid access to the core skeleton of Tipifarnib was realized to demonstrate the utility of this protocol.

Authors have researched and developed a series of copper phthalocyanine derivatives as new highly active and reusable catalysts for the hydroxylation of (hetero)aryl halides. The perfluorinated copper phthalocyanine (CuPcF16) showed the highest activity for the hydroxylation of aryl iodide with an excellent yield (up to 98%) under low catalytic loading (0.5 mol% CuPcF16). Similarly, the hydroxylation of aryl bromides and aryl chlorides catalyzed by CuPcF16 also had high activity with 42-98% yield. Moreover, the recyclability of this catalyst can up to 6 times without significant loss in catalytic activity.

A silver(I) oxide-mediated synthesis of unsym. aromatic azoxy compounds was successfully achieved, wherein oxidative coupling reactions between aromatic amines and nitrosoarenes take place in ethanol under air. This reaction has very high economic value because silver(I) oxide is the only oxidant required and no other additive is needed. The resulted silver particles can be easily recovered, while the only other byproduct is water. This new procedure is compatible with various functional groups and proceeds under mild reaction conditions.
