Hydrolysis and desilylation reaction of 2-[(trimethylsilyl)methyl]acrylate (=2-[(trimethylsilyl)methyl]prop-2-enoate) derivatives were studied to evaluate the effect of the presence/absence of a further conjugating substituent (Schemes 3 and 4 and Tables 1 and 2). The substrates having a nonconjugating substituent at the acrylate moiety were stable to dilute alkali conditions, and afforded simple hydrolysis
研究了2-[((三甲基甲硅烷基)甲基]丙烯酸(= 2-[((三甲硅烷基)甲基]丙-2-烯酸酯)衍生物的水解和脱甲硅基反应,以评估是否存在其他偶联取代基的效果(方案3和4以及表1和2)。在丙烯酸酯部分具有非共轭取代基的底物在稀碱条件下是稳定的,并在浓碱条件下提供简单的水解产物。相反,水解和去甲硅烷基化反应都发生在丙烯酸酯骨架上带有共轭取代基的底物上。反应性的差异可以用中间阴离子的稳定性来解释。
