Abstract
Phosphaheteroallenes R-P=C=L, with L = N-heterocyclic carbenes (NHCs), can be viewed to a certain extent as phosphaisonitriles stabilized with NHCs, R-P=C:←L. The suitability of these molecules as ligands for coinage-metal ions was investigated and coordination through the central carbon center was observed in most cases. A combination of experiments, spectroscopic methods, and DFT calculations indicates the presence of a hidden electron pair at the carbon center of R-P=C:←L. Remarkably, this lone pair also inserts intramolecularly in C-H bonds showing the carbene-type reactivity which is expected for phosphaisonitriles.

Abstract
The reaction of a kinetically stabilized diphosphene (Mes*P=PMes*: Mes* = 2,4,6-tri-tert-butylphenyl) with an organolithium reagent and an acyl halide afforded the corresponding phosphanoxy-substituted phosphaethene [((phosphinidene)methoxy)phosphine] via sterically-promoted bond-cleavage of the P-P bond.
