containing non transferrable groups known to promote transmetallation were prepared by Grignard chemistry and enyne metathesis. These dienes participated in one pot metathesis/Diels-Alder reactions in regio- and diastereoselective fashions. Electron-rich alkenes showed the fastest rates in metathesis reactions, and ethylene, a commonly used metathesis promoter slowed enyne metathesis. 2-Pyridyldimethylsilyl
通过格氏化学和烯炔复分解制备了含有已知可促进金属转移作用的不可转移基团的2-硅取代的1,3-二烯。这些二烯以区域选择性和非对映选择性方式参与了一个锅置换/ Diels-Alder反应。富电子烯烃在复分解反应中显示出最快的速率,而乙烯(一种常用的复分解促进剂)减慢了烯炔的复分解。2-吡啶基二甲基甲硅烷基和2-噻吩基二甲基甲硅烷基取代的Diels-Alder环加合物参与了交叉偶联化学反应,并且2-噻吩基二甲基甲硅烷基取代的环加合物在非常温和的反应条件下进行了交叉偶联。
