A new family of heteroleptic bis-cyclometalated Ir complexes with formula [Ir(CN^ ) (NN^ )]Cl (CN^ =2-phenylpyridinate and NN^ =2,2'-dipyridylamine or N-benzylated 2,2'-dipyridylamines, were synthesized, characterized, and successfully used as photosensitizers in the catalytic photooxidation of an array of dialkyl, dibenzyl, alkyl aryl, and diaryl sulfides, as well as sulfur-containing amino acids. Furthermore, the reactions proceeded with optimal chemoselectivity, and atom economy under mild conditions. Experimental observations support a dual mechanism in which singlet oxygen and superoxide are the actual oxidants.
一种新的异双核双环金属铱配合物家族，其通式为[Ir(CN^ ) (NN^ )]Cl（CN^ =2-苯基吡啶酸盐，NN^ =2,2'-联吡啶胺或 N-苄基 2,2'-联吡啶胺），已被合成、表征，并成功用作一系列二烷基、二苄基、烷基芳基和二芳基硫醚以及含硫氨基酸的催化光氧化的光敏剂。此外，这些反应在温和条件下以最佳的化学选择性和原子经济性进行。实验观察结果支持了一种双重机制，其中单线态氧和超氧化物是实际的氧化剂。
