A visible light mediated, metal-free process for the thiocyanation of imidazoheterocycles has been developed using eosin Y as a photoredox catalyst under ambient air at room temperature. A library of 3-(thiocyanato)imidazo[1,2-a]pyridines with broad functionalities have been synthesized in high yields. This methodology is also applicable for the selenocyanation of imidazo[1,2-a]pyridine.
已开发出一种可见光介导的、无金属的咪唑并杂环硫氰化方法，该方法在室温下的环境空气中使用曙红Y作为光氧化还原催化剂。一系列具有广泛官能团的3-(硫氰基)咪唑并[1,2-a]吡啶已被高产率合成。该方法也适用于咪唑并[1,2-a]吡啶的硒氰化反应。
