一般描述
三甲基氯硅烷是一种氯有机硅化合物，主要用于硅烷化反应。[1]
应用
三甲基氯硅烷（TMSCl）可用作：
- 试剂，通过形成三甲基硅基醚和三甲基硅基胺保护醇基和胺基。[2][3]
- 催化剂，用于制备抗菌剂1,3-二苯基-2-丙烯酮衍生物（查耳酮）。[3]
- 捕获剂，捕获偶姻缩合反应过程中产生的阴离子。[4]
- 更好的催化剂，替代有毒氯化汞，在烯丙型醇和α丙二烯型醇环丙烷化反应中活化钐（Sm）。[5]
- 催化剂，催化甘油三酸酯与醇进行酯交换反应形成脂肪酸烷基酯。[6]
- 试剂，和溴化锂一起将醇转化为相应溴化物。[7]
- 试剂，用于Fisher糖基化。[8]
- 酸催化剂来源，用于苯甲醛和Et3SiH进行还原苄化反应。[9]
- 试剂，与硫化钠反应合成三甲基硅硫醇钠(Me3SiSNa)；这一合成方案无味，可替代有恶臭气味的双(三甲基硫化硅)与甲氧基钠合成Me3SiSNa的方法。[10]
