The formation of a novel Lewis acid-base complex between the silyl azide Si(CH3)3N3 and GaCl3 having the formula (H3C)3SiN3·GaCl3 (1) is demonstrated. The X-ray crystal structure of 1 shows that the electron-donating site is the nitrogen atom directly bonded to the o...
近日,德国柏林工业大学Martin Oestreich课题组成功发展了通过硅正离子亲电活化S–Si试剂实现炔烃和联烯区域及非对映选择性硫硅双官能团化反应的新策略。策略的核心是利用高亲电性的硅正离子与S–Si试剂作用形成“双硅化的硫鎓离子(bissilylated sulfonium ion)”中间体,该中间体发挥传递硅亲电试剂的作用,也被证实是反应...
