Abstract
The direct hydroxylation of 2-arylpyridines and 2-arylbenzothiazoles via the merger of organic photoredox and metal catalysis is reported where 4CzIPN is used as the visible-light photocatalyst and Pd(OAc) as the metal catalyst. This method has been employed to synthesize organic molecules exhibiting excited-state intramolecular proton transfer properties for generating tunable luminescence responses.
摘要
本文报道了通过有机光氧化还原和金属催化的融合，实现 2-芳基吡啶和 2-芳基苯并噻唑的直接羟化，其中 4CzIPN 用作可见光光催化剂，Pd(OAc) 用作金属催化剂。该方法已用于合成具有激发态分子内质子转移性质的有机分子，以产生可调谐的发光响应。
