DIMERIC 2,2-DIMETHYL-2-SILABUT-3-ENYLDIPHENYLPHOSPHINECOPPER(I) BROMIDE : A CHELATING OLEFINIC-PHOSPHINE COPPER(I) COMPLEX

Abstract The reaction between CuBr 2 and 2,2-dimethyl-2-silabut-3-enyldiphenylphosphine (L 1 ) in methanol produced the title complex 1 ; the single crystal X-ray crystal structure of 1 reveals a centrosymmetric dimeric bromo-bridged species, with the copper(I) atoms bound to both the olefin and phosphorus donor sites on the ligands.
