When complexed to transition‐metal atoms , the zwitterionic ligand phenyl{bis(triphenylphosphanemethylenido)}borane behaves like a neutral analogue of the η 3 ‐allyl ligand. Syntheses and X‐ray crystal structures of the ligand and its complexes with ZrCl 4 and PdCl 2 (depicted) are described (Pd=cyan, B=yellow, P=pink, Cl=green, C=white).
