Addition of alkoxide ions resulted in ipso substitution in the photolysis of an alcohol solution of 1-(p-methoxyphenyl)-2,2-diphenylvinyl bromide, whereas addition of triethylamine, pyridine, or NaHCO3 led to vinylic substitution.
醇盐离子的添加导致 1-(对甲氧基苯基)-2,2-二苯基溴乙烯醇溶液光解中的 ipso 取代,而三乙胺、吡啶或 NaHCO3 的添加导致乙烯基取代。
