It is aimed to provide a cost effective p-NBSA catalyzed nucleophilic substitution of propargyl alcohols with alcohols, amines and heterocycles, without employing corrosive and costly metal catalysts, toxic solvents and column chromatography for purification. A systematic study of CC, CN and CO bond formation and efficacy of the scalability have also been confirmed.
目的是提供一种经济有效的对-NBSA催化的炔丙醇用醇,胺和杂环进行亲核取代,而无需使用腐蚀性和昂贵的金属催化剂,有毒溶剂和柱色谱法进行纯化的方法。还已经对C C,C N和C O键的形成以及可扩展性的功效进行了系统的研究。
