10-hexahydro-1,14-epithiodibenzo[b,j]thiacycloundecine-5,10-diol) as a model compound in which the 1- and 9-positions of thianthrene are bridged by a carbon chain. Dithianthren-1-ylmethanol and 1,1′-methylenedithianthrene were prepared and their reactions were studied. Lithiation of 1,1′-methylenedithianthrene took place on the methylene carbon rather than on the thianthrene framework, and when the lithiated derivative
摘要 制备了二噻吩-1-基甲醇和1,1'-亚甲基二噻吩并对其反应进行了研究。1,1'-亚甲基二噻蒽的锂化反应发生在亚甲基碳而不是噻吩骨架上,当锂化衍生物与噻吩-1-基甲醛反应时,位阻1,2,2-三噻吩-1-基乙醇以高收率获得。通过X射线晶体学确认了1,1′-亚甲基二硫蒽和1,2,2-三噻吩-1-基乙醇的结构。为阐明噻吨衍生物的性质和反应活性,我们还制备了1,6-(噻吨-1,9-二基)己烷-1,6-二醇(5,6,7,8,9,10-六氢-1, 14-乙硫基二苯并[ b,j[噻硫基环十一烷-5,10-二醇]作为模型化合物,其中噻蒽的1和9位通过碳链桥接。 制备了二噻吩-1-基甲醇和1,1'-亚甲基二噻吩并对其反应进行了研究。1,1'-亚甲基二噻蒽的锂化反应发生在亚甲基碳而不是噻吩骨架上,当锂化衍生物与噻吩-1-基甲醛反应时,位阻1,2,2-三噻吩-1-基乙醇以高收率获得。通过X射线晶体学确认了1
