A simple, efficient, and practical protocol is reported, allowing quick access to diverse 2-arylquinolines from 2-vinylanilines and benzyl halides. This reaction is additive and metal catalyst-free with only solvent needed. A preliminary mechanistic investigation discloses the driving force comes from the in situ released HBr, which catalyzes the subsequent cyclization. The present synthetic route
                                    报告了一种简单、有效且实用的方案,允许从 2-
乙烯基苯胺和苄基卤化物中快速获取各种 2-芳基
喹啉。该反应不含添加剂和
金属催化剂,仅需要溶剂。初步的机理研究表明,驱动力来自原位释放的 HBr,它催化了随后的环化。目前的合成路线具有高官能团耐受性和简单的后处理。各种 2-芳基
喹啉的收率高达 96%。
