β¦ Synopsis
Carbon-13NMR data recorded in the pulsed Fourier transform mode are reported for 1-and 2-naphthyltrimethylstannanes and 9-phenanthryltrimethylstannane. Assignments of ring carbon resonances are based on magnitudes of tin-carbon spin-spin coupling constants, substituent chemical shifts, spin-lattice relaxation times and proton coupled spectra.
