摘要: Abstract Organotin derivatives of 1-organo-5-thiotetrazole (RN 4 CS) have been synthesised by two methods: (i) a cycloaddition reaction between Bu 3 SnN and RNCS, (ii) the sodium salt preformed tetrazole an organotin halide. The structure 2 Sn(SCN Ph) has determined, ligand shown to be in thio form, attached tin through sulphur, rather than nitrogen as previously reported. An analysis azide-isothiocyanide based upon molecular orbital calculations is presented.
