Facile activation of homoatomic σ bonds in white phosphorus and diborane by a diboraallene

Metal‐free activation of homoatomic E−E σ bonds (E=P, B) in white phosphorus (P4) and bis(catecholato)diboron (B2cat2) with a 1,2‐diboraallene 1 is reported. The 1:1 and 1:2 reactions of P4 with 1 afford BnP4 cages (2: n=2, 3: n=4), whereas a stoichiometric mixture of 1 and B2cat2 undergoes homonucl...
