Phosphane-Tetrahalodiborane(4) Adducts: Formation of closo-3,4,5,6-Tetrabromo-1,2-diphosphahexaborane(4)

Tetrabromodiborane(4), B2Br4, forms a 1:2 adduct 1 with PBr3, which reacts at 350 deg C to closo-1,2-P2B4Br4 (4a) in 25percent yield.Compound 4a neither rearranges to the 1,6-isomer nor decomposes to an appreciable extent upon heating to 650 deg C.B2Cl4 reacts with equimolar amounts of either tris(trimethylsilyl)phosphane or 1,2-bis(dichlorophosphanyl)ethane to give B2Cl4*P(SiMe3)3 (2) and B2Cl4*Cl2PCH2CH2PCl2 (3), respectively.Compound 2 represents the first phosphane-diborane(4) monoadduct with two boron atoms in different coordination environment.Key Words: Bis(tribromophosphane)-tetrabromodiborane(4) diadduct / closo-3,4,5,6-Tetrabromo-1,2-phosphahexaborane(4)
