摘要:

AbstractThe chemistry of various sulfur‐transfer agents is studied. The reaction of aromatic sulfenyl chloride5in the presence of imidazole and/or triethylamine gives the aryl disulfides7in 14–85 percent yield, whereas in the case of the corresponding benzylsulfenyl chlorides9in the presence of triethylamine and/or caprolactam, both disulfide10and benzyl chlorides11are formed in 0–81 percent and 10–72 percent yield, respectively. – The transfer reactions of 3‐sulfenylated hydantoins18with amines are useful for the preparation of the unsymmetric sulfenamides20in 31–61% yield. Analogous transfer reactions of compounds23and24with piperidine giveN,N′‐thiodipiperidine (3, X
