2-(TRIMETHYLSILOXY)-1,3-CYCLOHEXADIENE Chemical Properties,Usage,Production

Uses

2-(Trimethylsiloxy)-1,3-cyclohexadiene may be used as a diene in the synthesis of isoquinuclidinone 2-aza[2.2.2]octa-3,5-dione by reacting with p-toluenesulfonyl cyanide.

General Description

2-(Trimethylsiloxy)-1,3-cyclohexadiene ((cyclohexa-1,5-dien-1-yloxy)trimethylsilane) is silyl enol ether of cyclohexenone. The Diels–Alder reactions with dienophiles α-acetoxyacrylonitrile, acrylonitrile and α-chloroacrylonitrile has been studied.
