Abstract

original image

Piecing together a carbonyl-decorated carbene and P4 affords the two transient diphosphenes (puzzle pieces in foreground) that rapidly dimerize to give a P8 allotrope (X-ray structure). Whereas nucleophilic carbenes stabilize main-group allotropes, in their Communication on page 4462 ff., T. W. Hudnall and co-workers show how the electrophilicity of carbenes dictates reactivity toward P4. By modulating carbene electrophilicity, two allotropes of phosphorus can be isolated and characterized.
