ORGANOMETALLIC COMPOUNDS OF COPPER .8. STUDIES ON COORDINATION CHEMISTRY OF HETEROATOM-BRIDGED BISALKYNES - COPPER(I) HALIDE AND COPPER(I) TRIFLUOROMETHYLSULFONATE COMPLEXES [German]

摘要

The first organometallic coordination compounds of heteroatom-bridged bisalkynes X(C=C)(2) (1) (X = S, OS, O2S or PhP) are reported. Ten new copper(I) complexes of these ligands with halides and trifluoromethylsulphonate as anions were synthesized and characterized. The copper(I) halide complexes 4-9 were prepared by direct reaction of the copper(I) halides and the free ligands 1. The copper(I) trifluoromethylsulphonate complexes 10-13 were synthesized from the ligand 1 and CuOSO2CF3 . O5C(6)H(6). The structures of these compounds, determined by spectroscopic and X-ray methods, show a variety of coordination types depending on the choice of the heteroatom X and the copper(I) fragment. In detail the following complexes were synthesized: [(CuCl)(4) . 2S(C=C(CH3)(3))(2)](n) (4); (CuCl)(4) . 20S(C=CC(CH3)(3))(2) (5); CuCl . PhP(C=CC(CH3)(3))(2) (6), CuA . 3PhP(C=CC(CH3)(3))(2) (A = Cl (7) or Br (8)); CuI . 2PhP(C=CC(CH3)(3))(2) (9), (CuOSO2CF3)(2) . X(C=CC(CH3)(3))(2) (X = S (10); OS (11) or O2S (12)); CuOSO2CF3 . Ph(C=CC(CH3)(3))(2) (13). The structure of 4 was determined by X-ray crystallography. [References: 30]
