Utilization of the novel Selective Population Transfer (SPT) technique for the first NMR observation of 29Si nuclei directly bound to transition metals is reported. Four metal carbonyl trimethylsilanes ((CH3)3SiMn(CO)5, (CH3)3SiRe(CO)5, (CH3)3SiCo(CO)4, and (CH3)3SiFe(CO)2(C5H5)) have been studied and their chemical shifts and coupling constants obtained. These data are compared with existing 29Si NMR spectra of more conventional (CH3)3SiX compounds and 119Sn NMR spectra of homologous (CH3)3Snmetal complexes. © 1979.
