Preparation of Primary Amides from Functionalized Organozinc Halides
摘要:
Organozinc halides, which are prepared either by direct zinc insertion or halogen magnesium exchange and subsequent transmetalation with ZnCl2, react smoothly with commercially available trichloroacetyl isocyanate to give, after hydrolysis, the corresponding primary amides. This method is compatible with a variety of functional groups such as an ester or a cyano group. Also heterocyclic-, alkenyl, and acetylenic zinc reagents are converted to the corresponding primary amides under these conditions.
