New Organophosphorus Ligands: 1,1,4,4-Tetrakis(diphenylphosphanyl)butatriene and Its Tetrasulfide

Treatment of bis(diphenylphosphanyl)ethyne with potassium diphenylphosphide in tetrahydrofuran leads to the formation of tetraphenyldiphosphane Ph2P-PPh2 and the title compound (Ph2P)2C=C=C=C(PPh2)2 (1).A mechanism is proposed for this process.Compound 1 reacts with elemental sulfur to give the tetrasulfide 2C=C=C=C2 (2).The crystal structures of 1 and 2 have been determined by single-crystal X-ray diffraction.In both cases the linear butatriene unit shows strongly alternating C=C bond lengths as predicted in theoretical studies. - Key Words: Butatriene, phosphanyl-substituted / Phosphane ligands / Phosphane sulfide
