摘要: 5-氢-1,9-二氧-4,6-二氮-5-膦螺[4,4]壬烷1在过量乙醇作用下与二硫化碳、异硫氰酸酯于室温下反应分别得到2-巯基二氢噻唑2和2-取代亚氨基四氢噻唑4a或二氢噻唑4b。此反应的机理为化合物1首先与乙醇进行酯交换形成三配位磷化合物,进而与不饱和键加成。

关键词: 膦螺烷, 异硫氰酸酯, 二氢塞唑, 四氢噻唑

Abstract: 5-Hydro-1, 9-dioxa-4, 6-diaza-5-phosphaspiro[4, 4]nonane(1) reacted with carbon bisulfide or isothiocyanates at room temperature in the presence of excessive ethyl alcohol to give 2-mercaptothiazoline (2) and 2-substituted iminothiazolidines (4a) or aminothiazolines (4b) respectively.The mechanism of this reaction might involve that compound 1 reacted with ethyl alcohol via the exchange ester route to form a three coordinated phosphorous compound, which then added to the unsaturated bond.

Key words: Spirophosphoranes, Isothiocyanates, Thiazolines, Thiazolidines
