A straightforward, mild, efficient, and environmentally benign protocol for a three-component Strecker reaction of aldehydes or ketones, amines, and trimethylsilyl cyanide catalyzed by sulfated polyborate has been described to afford α-aminonitriles under solvent-free reaction conditions. The major advantages of the present method are excellent yields, shorter reaction time, simple experimental procedure
已经描述了一种简单,温和,有效和对环境有益的方案,用于在无溶剂反应条件下,由硫酸化多硼酸酯催化的醛或酮,胺和三甲基甲硅烷基氰化物的三组分Strecker反应。本方法的主要优点是优异的收率,较短的反应时间,简单的实验步骤,容易的后处理步骤,催化剂的可回收性,无溶剂的反应条件以及耐受各种官能团的能力,这带来了经济上和生态上的回报。 。
