photosensitizers for photoredox catalytic transformations was investigated. While Zr(MeCNN)2 readily promotes the photochemical homocoupling of benzyl bromide in the presence of a sacrificial benzimidazolium hydride reductant, Zr(HCNN)2 undergoes an intramolecular photochemical reaction with formation of a new carbon–carbon bond between the phenyl units of the two HCNN ligands.
通过配体前体2-苯基-6-(5-甲基-3-苯基-1 H-吡咯-2-基)吡啶H的反应制备Zr(H CNN)2和Zr(Me CNN)2配合物2 H CNN和2-(3,5-二甲基-苯基)-6-(5-甲基-3-苯基-1 H-吡咯-2-基)吡啶,H 2 MeCNN,带有四苄基锆。两种络合物在可见光激发下都是光致发光的,并且在室温下在溶液中表现出数十至数百微秒的非常长的发射寿命。使用密度泛函理论研究了发射态的性质,该理论允许将其分配为主要为配体内部的三重态,并具有显着的配体-金属电荷转移贡献(3 IL / 3 LMCT)。电化学研究表明,每种配合物都有两个完全可逆的单电子还原反应,而对于受空间保护程度更高的配合物Zr(Me CNN)2则有一个附加的可逆氧化EC过程。。基于光学和电化学性质,研究了两种锆配合物作为光敏剂用于光氧化还原催化转化的效用。在牺牲性苯并咪唑鎓氢化物还原剂的存在下,Zr(Me CN
