Oxidative Alkylation

A new cobalt-catalyzed oxidative alkylation from readily available styrenes and ethers has been disclosed for a rapid and highly efficient construction of C−C bond via sp3 C−H bond functionalization. This methodology was demonstrated by good yields and functional group compatibility with simple operation, easily available starting materials, low catalyst loadings, and mild aerobic conditions.

AbstractWe herein report a new nitrogen-directed Rh(III)-catalyzed C(sp2)–H bond functionalization of N-nitrosoanilines and azoxybenzenes with maleimides as a coupling partner, in which the olefination/alkylation process can be finely controlled at room temperature by variation of the reaction conditions. This method shows excellent functional group tolerance, and presents a mild access to the resulting olefination/alkylation products in moderate to good yields.
