Abstract

Ethyl halodiazoacetates react with a range of substrates in regioselective rhodium(II)-catalysed C-H and Si-H insertion reactions­ giving α-halocarbonyl products in up to 82% yield. The halodiazoacetates are a novel class of diazo compounds that can undergo intermolecular carbenoid C-H insertion reactions, thus broadening the synthetic utility of such reactions.
