Abstract
A highly regioselective and stereoselective addition of alkyl bromides (amino-brominated aromatic β,β-dicyanoalkenes) to arylacetylenes by photoredox catalysis was developed. This difunctionalization of arylacetylenes was accomplished under ambient and metal-free conditions to produce alkenyl bromides in high efficiency with a wide range of group tolerance.
摘要
通过光氧化还原催化，发展了高区域和立体选择性的烷基溴化物（氨基溴化芳香族β，β-二氰基烯）对芳基乙炔的加成反应。在环境和无金属条件下实现了芳基乙炔的双官能化，以高效率、广泛的基团容忍度得到了烯基溴化物。
