GROUP IVB ORGANOMETALLIC DERIVATIVES: SYNTHESIS AND 13C NMR SPECTRA OF NEW SILYL AND STANNYL ISOXAZOLES

Article abstract of DOI:10.1016/S0022-328X(00)93310-2

Several new organometallic isoxazoles, silylated and stannylated in the heterocyclic ring or in a side chain have been made.Their 13C NMR spectra are consistent with the previous conclusions on the electronic effects of MR3 and CH2MR3 (M=Si, Sn) groups, and indicate the importance of the p_?-d_? and ?-? mechanisms in the various ring positions.
