Lawesson reagent 1 reacts with Mannich bases of β-naphthol 2 and 8-hydroxyquinoline 4 to give oxthiaphosphinine-3-sulfide derivatives 3 and 5, respectively. Reaction of 1 with benzaldehyde in the presence of trialkyl phosphite yields 1,3,5,2-trithiaphosphinane-2-sulfide derivative 8 and, in the presence of ethyl acrylate, affords 2,4,6-triphenyl-1,3,5-trithiane 9. A mechanism is proposed to explain
