Inherent directing group enabled, Co(III)-catalyzed C-H allylation/ vi-nylation of isoquinolones

The site-selective C8-allylation and vinylation of isoquinolones have been accomplished using allyl acetate and vinyl acetate and oxo group of isoquinolone as an inherent directing group in the presence of Co(III) catalysis. A plausible mechanism for the developed reaction has also been delineated based on preliminary mechanistic studies. Broad substrate scope with good to excellent yield and post-synthetic transformations of allyl and vinyl products feature the importance of reaction.
