The addition of isocyanicles to acyl chlorides (isocyanide-Nef reaction) leads to imidoyl chlorides which can later be treated with trialkylphosphites to afford new keteneimines in a Perkow-type reaction. The whole sequence may be performed without any solvent, and the resulting keteneimine may easily be converted to phosphorylated tetrazoles and triazoles.

The ketenimines resulting from a Nef isocyanide/Perkow sequence react with 1-azadienes to form pyridines or pyrimidines depending on their substitution pattern. The reaction is most efficient with ester-substituted ketenimines which leads to pyridines after elimination of the phosphate group. (C) 2011 Elsevier Ltd. All rights reserved.

A one-pot, four-component synthesis of imido phosphates has been achieved using a Nef–Perkow sequence followed by addition of carboxylic acid derivatives. The final imido moiety is formed via a Mumm rearrangement of an intermediate imidate.
