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。
Isolation and alcoholysis of an ipso adduct, vinylidenecyclohexadiene, from photolysis of 1-(p-ethoxyphenyl)vinyl bromide
An ipso adduct, vinylidenecyclohexadiene , was isolated from the title photolysis and showed exclusive transformation to the corresponding vinyl ethers by alcoholysis.
从标题光解中分离出ipso加合物,亚乙烯基亚环己二烯,并显示通过醇解作用独家转化为相应的乙烯基醚。
