A copper-catalysed direct radical alkenylation of benzyl bromides and α-carbonyl alkyl bromides has been developed. Compared with recent radical alkenylations which mostly focused on secondary or tertiary alkyl halides, this transformation shows good reactivity towards primary alkyl halides and tertiary/secondary alkyl halides are also tolerated.

We report the synthesis of 1,4-dicarbonyl compounds and substituted alkenes (Mizoroki–Heck type coupling) starting from secondary and tertiary alkyl halides and vinyl acetate or styrene derivatives using visible-light photocatalysis.

An efficient and broadly applicable process is reported for the direct alkylation of heteroarene C–H bonds, based on the copper-catalyzed addition of alkyl radicals generated from activated secondary and tertiary alkyl bromides to a range of arenes, and their benzo-fused derivatives.
