aminomethyltrialkylsilanes have been studied for their ability to undergo metalation between nitrogen and silicon, followed by reaction with an electrophile. Metalation is rapid and reaction with a variety of electrophiles proceeds efficiently. When a benzyl group is attached to nitrogen, benzylic deprotonation competes with deprotonation next to silicon.
已经研究了容易获得的氨基甲基三烷基硅烷的氨基甲酸叔丁酯衍生物在氮和硅之间经历金属化,然后与亲电试剂反应的能力。金属化迅速,并且与各种亲电试剂的反应有效地进行。当苄基连接到氮上时,苄基去质子化与硅旁边的去质子竞争。
