Stoichiometric removal of ligand from phosphine-ligated copper(I) reagents with BH3 · Thf: a novel synthesis of di-μ-bromotetrakis(methyldiphenylphosphine)-dicopper(I) and the structures of CuBr[PMePh2]3 and {CuBr [PMePh2]2}2
摘要:
Attempts to synthesize CuBr[PMePh2]2 using standard methods result in the formation of CuBr[PMePh2]3 (I). {CuBr[PMePh2]2}2 (II) has been conveniently prepared in high yield from I by the reaction with BH3 . THF in THF, and its molecular structure has been determined. {CuBr[PMePh2]2}2 (II) crystallizes in the triclinic space group P1BAR with cell dimensions a = 10.362(4), b = 10.938(5), c = 12.620(6) angstrom, alpha = 74.90(4), beta = 67.81(3), gamma = 87.91(3)-degrees and Z = 2 (per monomeric unit). The molecule II is a dibromide-bridged dimer with two pseudo-tetrahedral copper atoms. The molecular structure of CuBr[PMePh2]3 (I) is also reported. The species crystallizes in the orthorhombic space group Pna2(1) with Z = 4 and cell constants a = 20.174(7), b = 10.354(3) and c = 17.267(5) angstrom. The coordination geometry about the copper atom is approximately tetrahedral. Detailed spectroscopic data are reported for both species. This reaction involving removal of phosphines with BH3 . THF appears to be stoichiometric and general.

The 16-electron copper(I) complexes [Cu(µ-1-BrB5H7)(PPh3)2] and [Cu(µ-B5H8)(dppe)](dppe = Ph2PCH2- CH2PPh2) have been prepared and shown to be similar to [Cu(µ-B5H8)(PPh3)2] whose structure has recently been established by single-crystal X-ray analysis. The corresponding silver(I) complex [Ag(µ-B5H8)(PPh3)2] has been prepared as a colourless photosensitive solid which decomposes fairly rapidly in solution
