Sterically unencumbered diborenes based on a benzylphosphine chelate undergo diboration reactions with bis(catecholato)diboron in the absence of a catalyst to yield tetraboranes. The symmetrical diborenes studied undergo 1,2‐diborations, whereas an unsymmetrical derivative was found to yield a triborylborane–phosphine adduct as the result of a formal 1,1‐diboration. A related borylborylene compound also underwent a 1,2‐diboration to produce a borylene–borane adduct.
