摘要
5-氢-1,9-二氧-4,6-二氮-5-膦环-[4,4]壬烷1与二硫化碳、异硫氰酸酯反应,分别得到2-巯基二氢噻唑2和2-取代氨基二氢噻唑4,并用动态^(31)P NMR谱研究了其反应机理。
The addition reaction of 5-hydro-1, 9-dioxa-4 , 6-diaza-5-phosphaspiro-[4, 4]-nonane 1 with carbon disulfide or isothiocyanates is accompanied by a rearrangement to produce 2-mercaptothia-zoline 2, and 2-substituted aminothiazolines 4 respectively. The mechanism of reaction may involve the addition of 1 and its tautomer 6 to the unsaturated bond.
