Synthesis and Structures of New 1,3,2,4-Diphosphadiboretanes

Three methods have been devised to prepare new diphosphadiboretanes: a) Base-induced hydrogen halide elimination from (amino)phosphinoboron halides precursors, b) tris(trimethylsilyl)phosphane elimination from R2N-B2 intermediates prepared in situ from combination of R2N-B(Cl)-P(SiMe3)2 and LiP(SiMe3)2, and organylphosphane elimination from aminobis(organylphosphino)boranes R2N-B(PHR')2.The molecular structures of three new 1,3,2,4-diphosphadiboretanes (3, 4a, 4c) were determined by X-ray diffractometry.These are characterized by a planar four-membered B2P2 ring with the phosphorus substituents in trans positions.Their BP bomnds represent single bond distances.Experimental results are compared with MNDO III calculations which reveal a low barrier (ΔE = 5 kcal/mol) for the dimerization of the boraphosphane H2N-B=PMe to the diphospadiboretane (H2N-BPMe)2.
