In the presence of THF and H 2O(9∶1),α benzotriazole sulfides are synthesized via the reaction of 1 Chloromethyl benzotriazole with disulfides promoted by Sm/CdCl 2.The process is convenient with yield 82~91%.
The title compounds was synthesized by the fluorination reaction of Dialkylaminosulfur trifluoride(DAST) with 1(4alkylphenyl acetyl)4alkylphenyl.The reaction was carried out in ethyleneglycol dimethyl ether at...The title compounds was synthesized by the fluorination reaction of Dialkylaminosulfur trifluoride(DAST) with 1(4alkylphenyl acetyl)4alkylphenyl.The reaction was carried out in ethyleneglycol dimethyl ether at 80℃ for 24h with conversion 95%and yield 42%~50%.The influence of quantity of DAST,temperature and solvent was investigated.展开更多
