α-Phenylselanyl aldehydes are prepared on a large scale by reaction of PhSeCl3 with the corresponding aldehydes in acetonitrile without isolation of the intermediate dichloro adducts. This method has been applied to α-phenylselanyl ketones derived from alkyl aryl ketones, symmetrical aliphatic ketones and alkyl isopropyl ketones. cis-4-tert-Butyl-2-phenylselanylcyclohexanone was also prepared in the same way.
α-苯硒基醛通过PhSeCl3与相应醛在乙腈中反应大规模制备,无需分离二氯加成中间体。该方法已应用于由烷基芳基酮、对称脂肪酮和烷基异丙基酮衍生的α-苯硒基酮,并同样制备了顺-4-叔丁基-2-苯硒基环己酮。
