The first monomeric tetraalkylphosphinoboranetBu2B=PtBu2 was synthesized from tBu2BBr and LiPtBu2.It decomposes above -20 deg C via double retro-hydroboration and elimination of isobutene, undergoes subsequent re-hydroboration and dimerisation to give stable bis(phosphinoborane)iBu(H)PtBu2>2, whose molecular structure was determined by X-ray diffraction.It containes planar, almost square (BP)2 four-membered ring.The B-P distances are 2.004(4)/2.022(4) Angstroem.The first monomeric triphosphinoborane Me2PB(PMes2)2, was synthesized similarly.All compounds have been characterized by NMR spectroscopy.
