A scalable approach for the cyanosilation of benzaldehydes and acetophenones using indium trichloride, a versatile,
user friendly catalyst is developed. Cyanohydrin trimethylsilyl ethers are converted in the same pot to α-fluorophenyl acetonitriles which are efficiently reduced to their corresponding amines using sodium borohydride in presence
of cerium trichloride.
本研究开发了一种可扩展的方法,利用三氯化铟这种用途广泛、使用方便的催化剂对苯甲醛和苯乙酮进行氰化反应。氰醇三甲基硅基醚在同一锅中转化为 α-氟苯基乙腈,然后在三氯化铈存在下使用硼氢化钠高效还原为相应的胺。
