塩化鉄(III)を触媒とずる置換ベンジリデン=ジクロリドとヘキサメチルジシロキサンとの反応による置換ベンズアルデヒドの簡便な合成

The iron(III) chloride-catalyzed reaction of benzylidene dichlorides with hexamethyldisiloxane was found to give benzaldehydes in good isolated yields of 65∼74%. Isophthalaldehyde was also given from the reaction of a, a, a', a'-tetrachloro-m-xylene with siloxane in 40% yield. From the reaction of diphenyldichloromethane benzophenone was obtained i n 78% yield. A plausible pathway leading to aldehyde is presented.
