Abstract

Abstract Cyclothiomethylation of phenyl hydrazine with CH 2 O and H 2 S in a ratio of 1: 3: 2 in an acidic medium (HCl) afforded previously unknown 3-phenyl-1, 3, 4-thiadiazolidine (35% yield) and N-phenyl (perhydro-1, 3, 5-dithiazin-5-yl) amine (35% yield). The analogous reaction in an alkaline medium (BuONa) produced N-phenyl (perhydro-1, 3-thiazetidin-3-yl) amine (22% yield). The reaction of 1, 2-diphenyl hydrazine with CH 2 O and H 2 S in an ...
