New S-thiocarbamates possessing a 10,11-dihydro-5H-dibenzo[a,d]cycloheptene moiety were obtained unexpectedly in the process of preparing new O-thiocarbamates starting from 5-dibenzosuberol (10,11-dihydro-5H-dibenzo[a,d]cyclohepten-5-ol) and aroyl-isothiocyanates. These compounds were obtained via a benzylic Newman–Kwart rearrangement mechanism. The structures of the new thiocarbamates were confirmed
新小号-thiocarbamates具有一个10,11-二氢-5- ħ -二苯并[一,d ]的制备新的方法出乎意料地得到环庚烯基部分ö -thiocarbamates由5- dibenzosuberol(10,11-二氢-5-开始ħ -二苯并[ a,d ]环庚烯-5-醇)和芳酰基-异硫氰酸酯。这些化合物是通过苄基Newman-Kwart重排机制获得的。新的硫代氨基甲酸酯的结构通过元素分析,IR和NMR光谱以及X射线晶体学证实。
