The reactions of 1-arylethene, 1,1-diarylethenes, and 1,1-diarylpropenes with iodine(III) tris(trifluoroacetate) gave 1,2-diaryl-1-alkanones, 1-aryl-2-(4-iodophenyl)-1-alkanones, benzoins, benzils, and iodoethenes. A similar reaction of 1,1,4,4-tetraaryl-1,3-butadiene yielded 1,2,4,4-tetraaryl-3-buten-1-one. The reactions of 1,1,5,5-tetraaryl-1,4-pentadienes and 1,1,6,6-tetraaryl-1,5-hexadienes also gave dicarbonyl compounds. The reaction involves aryl migration. The mechanisms and the utility of the reaction for organic synthesis are discussed.
1- 芳基烯、1,1- 二芳基烯和 1,1- 二芳基丙烯与碘(III)三(三氟乙酸盐)反应生成 1,2- 二芳基-1-烷酮、1-芳基-2-(4-碘苯基)-1-烷酮、安息香、苯并芘和碘乙烯。1,1,4,4-四芳基-1,3-丁二烯的类似反应生成 1,2,4,4-四芳基-3-丁烯-1-酮。1,1,5,5-四芳基-1,4-戊二烯和 1,1,6,6-四芳基-1,5-己二烯的反应也生成了二羰基化合物。该反应涉及芳基迁移。本文讨论了该反应的机理和在有机合成中的用途。
