Abstract: The mannich-type reactions of phenylthiourea with phenyl dichlorophosphine and aldehydes (ketones) are investigated.Besides the expected products, 3,4-diphenyl-1,3,4-diaza-phospholidin-2-thione-4-oxides, small amounts of new products, the corresponding 4-sulfides were isolated and characterized.Some structure information of the products are disclosed.Amechanism involving addition of P-Hto the imine derivatives is proposed for the reactions.

Key words: Mannich-type reaction, Synthesis, 1,3,4-diazaphospholidin-2-thione, Reaction mechanism
