The general pathway to 1,2-monoheterophosphacyclanes via intramolecular S-and N-alkylation of ω-halogenoalkylsubstituted thiophosphoryl and iminophosphoryl compounds has been developed. Intramolecular alkylation of 3-and 4-halogenoalkyldiphenylphosphine sulfides results in 1,2λ4-thiaphospholanium and thiaphosphorinanium halogenides. In solution of these compounds the rare ring-chain halogenotropic tautomerism has been observed and investigated in detail. Intramolecular Pishchimuka rearrangement of the esters of ω-halogenoalkylsubstituted thiophosphorus acids was found to be a synthetic route to 2-oxo-1,2ω5-thiaphospholanes and thiaphosphorinanes.
