Novel fused (cis-octahydrothienothiepine, cis-hexahydrothieno-1,4-oxathiine and cis-hexahydrothieno-1,4-dithiine) and spiro (1,4,6-trithiaspirononane and 1,4,7-trithiaspirononane) bicyclic compounds containing sulphur have been synthesized and their structures confirmed by NMR spectroscopy.For their synthesis, reactions of nucleophiles, including Grignard reagents, with trans-2,3-dichlorotetrahydrothiophene were investigated.Improved methods of forming sulphides from Na2S and haloalkanes have been developed. 1-Bromo-4-chlorobutane was shown to form the specific Grignard reagent, Cl4MgBr.
