Acyl oximes are directly used as the acyl radical precursors in the hydroacylation reactions for the first time. In this work, acyl radicals can be effectively generated via β-scission of a phosphoranyl radical under photocatalytic conditions. As a result, the hydroacylation of alkenes triggered by the resulting acyl radicals leads to facile syntheses of a range of valuable ketones.

A copper-mediated annulation protocol of new (ortho-arylethynyl)phenyl enaminones bearing a N,N-dimethylamine moiety was developed to facilely install a series of α-aminonaphthalene derivatives. Simple manuipulation of exogenous amine readily offers the...
