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.

We present herein a new access to indolizine derivatives involving 1,3-dipolar cycloaddition of pyridinium ylides with phosphorylated hydroxyketenimines. These ketenimines are easily formed via a Nef-Perkow cascade involving isocyanides as starting material.
