Intramolecular S-alkylation in a series of ω-haloalkyl-substituted thiophosphorylacetonitriles 5–7 presents an effective synthetic route to the hitherto unknown 3-cyano-2-oxo-1,2-thiaphospholanes 14 and thiaphosphinanes 15. The compounds were obtained as a mixture of cis- and trans-isomers that were resolved to individual stereoisomers in most cases. For some of them, X-ray diffraction analysis has
