Abstract

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 B_nP₄ cages (2: n=2, 3: n=4), whereas a stoichiometric mixture of 1 and B₂cat₂ undergoes homonuclear catenation through the addition of the B−B σ bond of B₂cat₂ across the B=B double bond of 1 (i.e. diboration), which leads to the formation of a tetraborane (4) featuring a B₄ chain.
