Notes:
Tetrabromodiborane(4), B2Br4, forms a 1:2 adduct 1 with PBr3, which reacts at 350°C to closo-1,2-P2B4Br4 (4a) in 25% yield. Compound 4a neither rearranges to the 1,6-isomer nor decomposes to an appreciable extent upon heating to 650°C. B2C14 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.
