α-Nitro-β-iodo(sulfanyl)ethenes in reactions with N,S-binucleophiles
摘要:
alpha-Nitro-beta-iodo(sulfanyl)ethenes were brought into reactions with N,S-binucleophiles that completed with the replacement of the beta-functional group. Iodonitroethenes with thiourea and N,N'-diphenylthiourea provided products of S-substitution. The reaction of less reactive sulfanylnitrostyrene with N,N'-diphenylthiourea and also of iodonitrostyrene with 5-amino-benzothiazolyl-2-thiol required longer time and led to the formation of more stable products of N-substitution. The reactions with 5-aminobenzothiazolyl-2-thiolate in all events resulted in the products of S-substitution.
