Abstract
A visible/solar-light-induced electron-donor-acceptor (EDA)-aggregated/mediated radical cyclization between ()-2-(1,3-diarylallylidene)malononitriles and thiophenols leads to poly-functionalized pyridines. The two reacting partners form an EDA complex that absorbs light and triggers the single-electron transfer (SET) to generate a thiol radical, which undergoes addition/cyclization with dicyanodiene through the formation of C-S and C-N bonds.
摘要
()-2-(1,3-二芳基烯丙基亚甲腈)与噻吩之间可见/太阳光诱导的电子给体-受体（EDA）聚集/介导的自由基环化反应生成多官能化吡啶。两个反应试剂形成 EDA 络合物，吸收光并引发单电子转移（SET），生成硫自由基，该自由基通过 C-S 和 C-N 键的形成与二氰二烯加成/环化。
