Abstract

Abstract New heterocyclic thiophosphoric compounds containing the NCN sequence in the ring were prepared by the reaction of thiophosphoryl trichloride (PSCl 3) with N, N'- diphenylthiourea. Depending on the reaction conditions, two types of heterocyclic compounds were obtained, namely 2-chloro-1, 3-diphenyl-1, 3, 2λ 5-diazaphosphetidine-2, 4-dithione (1) and 2-chloro-1, 3, 5-triphenyl-1, 3, 5, 2λ 5-triazaphosphinane-2, 4, 6- ...
