Diphosphanylketenimines: New reagents for the synthesis of unique phosphorus heterocycles

Two consecutive [3+2] cyclo-addition reactions of the diphosphanyl-ketenimine (PPh2)2C=C=NPh (3), involving the phosphanyl groups, with two equivalents of the electron-poor alkynes dimethyl acetylenedicarboxylate or methyl acetylenec

Fully reversible cyclic dimerization of diphosphanylketenimines promoted by intramolecular C-H···N hydrogen bonds

Just by crystallization at room temperature the diphosphanylketenimine 1 is transformed into the unsymmetrical dimer 2 through a novel [2+3] cycloaddition reaction; a phosphanyl substituent is involved in the annelation process. This dimerization is fully reversible and appears to be promoted by intramolecular CH···N hydrogen bonds.
