ORGANOMETAL COMPOUNDS OF COPPER .9. MONONUCLEAR AND BINUCLEAR COPPER(I) BETA-DIKETONATE COMPLEXES WITH SULFUR-BRIDGED BISALKYNES - POTENTIAL PRECURSOR SYSTEMS FOR METAL-ORGANIC CHEMICAL VAPOR DEPOSITION [German]

摘要

In this paper the synthesis and characterization of six new copper(I)-beta-diketonate complexes, stabilized by heteroatom-bridged bisalkynes X(C=C(t)Bu)(2) (3), are reported: [(Cuhfac)(2).S(C=C(t)Bu)(2)] (4a), [(Cutfac)(2)S(C=C(t)Bu)(2)] (4b), [(Cuacac)(2).S(C=C(t)Bu)(2)] (4c), [(Cuthd)(2)s(C=C(t)Bu)(2)] (4d), [(Cuhfac)(2).OS(C=C(t)Bu)(2)] (5) and [Cuhfac.O2S(C=C(t)Bu)(2)] (6). Complex 4a is a volatile compound and could be an interesting dinuclear precursor in copper chemical vapor deposition. The structures of 4b-4d were determined by X-ray crystallography.
