SYNTHESIS AND SPECTROSCOPIC STUDIES OF SOME ORGANOTIN(IV) COMPOUNDS CONTAINING THE SN-O BOND

The preparation of a number of organotin(IV) compounds, containing SnO bonds, is described. Their 13C and 1H NMR, IR spectra, and some molecular weight determinations, are presented. Structures are postulated based largely on the one bond coupling constant 1J( 119 117Sn13C). Further evidence is obtained from 1H NMR and IR spectra. For the compounds reported, IR spectra do not appear to provide unambiguous evidence because of difficulties in assigning and interpreting CO, SnO and SnC stretch frequencies. © 1979.
