以易制备和无气味的3-(二乙硫/苄硫基)亚甲基-2,4-戊二酮1作乙硫醇和苄硫醇替代试剂,进行了环保和无气味的β-羰基硫醚的合成研究。在甲醇介质中,氯化乙酰存在下,1发生分解反应,释放出乙硫醇或苄硫醇,然后与α,β-不饱和酮2进行硫杂迈克尔加成反应,高产率生成β-羰基硫醚,反应过程无恶臭气味。 An environmentally friendly and odorless β-carbonyl group was synthesized using an easily prepared and odorless 3- (diethylthiol / benzylthio) methylene-2,4-pentanedione 1 as ethanethiol and benzylmercaptan substitution reagents Synthesis of Thioether. In methanol medium, the presence of acetyl chloride, 1 decomposition reaction, the release of ethanethiol or benzyl mercaptan, and α, β-unsaturated ketone 2 thio-Michael reaction, high yield β-carbonyl Thioether, the reaction process no foul smell.
