Abstract

The interaction of isocyanides with acyl chlorides was first reported by Nef in 1892. The resulting α-keto imidoyl chlorides may be hydrolyzed to form α-keto amides. Relatively few data are available on this reaction and the chemistry of α-keto imidoyl chlorides has been largely underestimated until some recent uses in intra­- and intermolecular couplings with a variety of nucleophiles. The present review brings a comprehensive presentation of the Nef reaction of isocyanides focusing on mechanism and regioselectivity issues.

  • 38 After deprotonation, the α-effect raises the energy of the nitrogen lone pair which is responsible for the dechlorination. The mechanism is reminiscent of those for the preparation of nitrile N-oxides via hydroximoyl chlorides.
