Abstract
The first syntheses of the novel [1,2]thiaphospholo[4,5-e][1,2,4]triazine r ing system, exemplified by the derivatives 3a-c have been accomplished by t he action of Lawesson's reagent on the 5-arylmethyl-1,2,4-triazin-6-ones 1a -c, their thiones 2a-c or the Mannich bases 4-6. The structure of these new thiaphospholotriazines was established mainly by NMR, and X-ray structural analysis. (C) 1999 Elsevier Science Ltd. All rights reserved.
