The first examples of carbene-cadmium complexes are reported from the reactions of a variety of imidazol-2-ylidenes or imidazolin-2-ylidenes with dimethylcadmium. Four new carbene complexes are characterized by NMR spectroscopy (1H , 13C and 113Cd). The cadmium centers are strongly shifted downfield (100 -150 ppm) by interaction with the carbenes. X-ray structures are reported for three carbene-cadmium 1:1 adducts. The cadmium centers exhibit distorted trigonal-planar geometries in which the carbene ligands have an average 18.2 pm longer bond distance to cadmium compared to the methyl groups. The planes of cadmium coordination are twisted with respect to the plane of the imidazole ring. The more basic imidazolin-2-ylidene is shown to displace imidazol-2-ylidenes from the cadmium center.

119Sn Nmr

The 13C and 119Sn NMR spectroscopy has been used to study the compounds types (C6H5CH2)4-nSn(CH3)n and (C6H5CH2)4-nSnCln (n = 0 - 3) in media of non-coordinating (deuteriochloroform) and coordinating (hexadeuteriomethyl sulphoxide) solvents. The analysis of the NMR data has confirmed the presence and established the relative extent of participation of the σ-π conjugative connection of the polarized σ(Sn-C) bond with the adjacent π electronic system of the aromatic ring in the Sn-CH2-C6H5 grouping. The extent of σ-π conjugation decreases with decreasing number of methyl groups in the compounds (C6H5CH2)4-nSn(CH3)n and with increasing number of chlorine atoms in the compounds (C6H5CH2)4-nSnCln and with increasing coordination number of the central tin atom in the complexes of the compounds (C6H5CH2)4-nSnCln.x(C2H3)2SO.
