Title compounds were synthesized by the reaction of 2,4,6-tri-t-butylthiobenzaldehyde with some diazomethanes. The photolysis of the most sterically congested episulfide obtained from t-Bu2CN2 gave an unusual product resulting from 1,2-migration of t-butyl group instead of the corresponding styrene, a normal photo-product, the corresponding styrene, together with Dewar benzene and benzothiophene derivatives.
标题化合物是由 2,4,6-三丁基硫代苯甲醛与一些重氮甲烷反应合成的。从 t-Bu2CN2 中得到的最立体拥塞的环硫化物在光解过程中产生了一种不寻常的产物,该产物是由叔丁基的 1,2 迁移产生的,而不是相应的苯乙烯、正常的光产物、相应的苯乙烯以及 Dewar 苯和苯并噻吩衍生物。
