Darstellung und Reaktionsverhalten von 2,2-Dithio-phosphol-und -phosphorinan-Derivaten

Synthesis and Reactions Behavior of 2,2-Dithiophospholes and 2,2-Dithiophosphorinanes Reaction of dithiophosphoric acid chloride betaine 1 with bifunctional compounds opens a new way for preparing five- or six-membered cyclic dithiophosphates ( 2a – i, 3, 5a – f ). Synthesis, spectroscopic properties, and some reactions of these compounds are reported. Reaction of the cyclic dithiophosphates with alkyl halides yields the corresponding S-alkylesters 6a – o .
