Isolation of a Neutral P sub(8) Cluster by [2+2] Cycloaddition of a Diphosphene Facilitated by Carbene Activation of White Phosphorus

P-cing it together: Carbonyl-decorated carbenes readily activate white phosphorus to afford carbene-stabilized P sub(4) and P sub(8) clusters. Mechanistic evidence suggests the P sub(8) cluster (see structure from X-ray diffraction: Cgray, Porange, Nblue, Ored) forms by a [2+2] cycloaddition of a tr...

Summary:P-cing it together: Carbonyl-decorated carbenes readily activate white phosphorus to afford carbene-stabilized P sub(4) and P sub(8) clusters. Mechanistic evidence suggests the P sub(8) cluster (see structure from X-ray diffraction: Cgray, Porange, Nblue, Ored) forms by a [2+2] cycloaddition of a transient diphosphene species.
