subnitrate is reported herein as a simple and efficient catalyst for the atom-economical synthesis of methyl ketones via Markovnikov-type alkyne hydration. Besides an effective batch process under reasonably mild conditions, a chemically intensified continuous flow protocol was also developed in a packed-bed system. The applicability of the methodologies was demonstrated through hydration of a diverse

亚硝酸铋作为通过马尔可夫尼科夫型
炔烃水合原子经济合成甲基酮的简单而有效的催化剂。除了在合理的温和条件下进行有效的分批处理外,还在填充床系统中开发了
化学强化连续流方案。该方法的适用性通过
水合各种末端
乙炔来证明。通过简单地将反应介质从
甲醇切换为
甲醇-d 4,还制备了有价值的三
氘代甲基酮。由于非均相催化剂的现成可用性和无毒性,从而消除了对任何特殊添加剂和/或有害试剂的需求,因此所提出的方法在实用性和可持续性方面显示出重大进展。
