Palladium-Catalyzed Oxidative Arylalkylation of Unactivated Alkenes: Dual C–H Bond Cleavage of Anilines and Acetonitrile
摘要:
A palladium-catalyzed oxidative arylalkylation of unactivated alkenes involving dual C-H bond cleavage of arene and acetonitrile was developed. This reaction was promoted by pyridine as a ligand, and the ratio of palladium to pyridine is vital for this transformation. A series of nitrile-containing indolines were efficiently provided in moderate to good yields.

A copper-catalyzed cascade denitrogenative transannulation/hydrolyzation of 3-aminoindazoles with N-(2-methylallypanilines was developed, affording a variety of 2-(aminomethyl)-2-methyl-indanones in moderate to good yields. 2-Cyanophenyl radical, which generated from oxidative denitrogenation of 3-aminoindazole, was proved as the reaction intermediate. This reaction features, along with the ready availability of starting materials, a cascade cleavage of two C-N bonds and construction of two C-C bonds in one pot.
