Heating of N-aryl-1, 2, 3, 4, 5, 7-pentathiazocanes 1 in the presence of primary and secondary amines afforded N-Alkyl or N, N-dialkylthioformamides 5, and similar heating of 1 in the absence of amines afforded an inseparable mixture of acyclic polysulfides 4 bearing a thioformanilide moiety on each terminal. Bisthioformanilides 4 were also converted into 5 by treating with these amines, and the thioformylation was assumed to proceed through a ...
