Ketones and aldehydes are converted to symmetrical and (E)-olefins (1-15) by reaction with 2,4-bis(phenyl)-1,3-diselenadiphosphetane-2,4-diselenide (PhPSe(2))(2), Woollins' reagent, in refluxing toluene; use of diketones was demonstrated by the reaction of PhC(O)CH(2)C(O)Ph which gives 1,2,4,5-tetraphenylbenzene (16) in 83% yield.
酮和醛通过与2,4-双(苯基)-1,3-二硒二氮杂环戊烷-2,4-二硒化物(PhPSe(2))(2)反应而转化为对称和(E)-烯烃(1-15) ,伍林斯的试剂,在回流的甲苯中;PhC(O)CH(2)C(O)Ph的反应证明了二酮的使用,该化合物以1,83%的产率得到1,2,4,5-四苯基苯(16)。
