Optimal conditions were found for induced hydroxyhalogenation of cyclic dienes (tetrahydroindene, 4-vinylcyclohexene and 5-vinyl- and 5-cyclohexenylbicyclo[2.2.1]hept-2-enes) in the system [MHlg-HA or HHlg]-H2O2 (or NaClO). Dehydrohalogenation of the chloro- and bromohydrins thus obtained with powdered potassium carbonate gave the corresponding diepoxy derivatives, and their hydrolysis led to mixtures
发现了在[MHlg-HA或HHlg] -H 2 O系统中诱导环二烯(四氢茚,4-乙烯基环己烯和5-乙烯基和5-环己烯基双环[2.2.1]庚-2-烯)的羟基卤化的最佳条件。2(或NaClO)。用粉末状碳酸钾将如此获得的氯代和溴代醇脱氢卤化,得到相应的二环氧衍生物,它们的水解导致形成立体异构的四元醇的混合物。
