Piecing together a carbonyl‐decorated carbene and P 4 affords the two transient diphosphenes (puzzle pieces in foreground) that rapidly dimerize to give a P 8 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 P 4 . By modulating carbene electrophilicity, two allotropes of phosphorus can be isolated and characterized.
