reacted with benzenethiol at 150 °C under radical conditions to give the adduct 2, the benzothiophene 4 and the indole 5. Reaction of 1 with benzenesulfanyl radicals produced from diphenyl disulfine in the absence of hydrogen donors gave only the indole 5 in high yields. Formation of indole 5 was explained in terms of sulfanyl radical mediated aminyl radical cyclization onto the alkyne triple bond.
1-(2-氨基苯并)戊-1-炔1在自由基条件下于150°C与苯硫醇反应,生成加合物2,苯并噻吩4和吲哚5。1与不存在氢供体的二苯基二硫产生的苯硫基自由基反应,仅以高收率得到吲哚5。吲哚5的形成是通过硫烷基自由基介导的氨基自由基环化到炔三键上来解释的。
