On May 18, 2018, Wang, Xu; He, Dandan; Huang, Yubing; Fan, Qihang; Wu, Wanqing; Jiang, Huanfeng published an article.Product Details of 157869-15-3 The title of the article was Copper-Catalyzed Synthesis of Substituted Quinazolines from Benzonitriles and 2-Ethynylanilines via Carbon-Carbon Bond Cleavage Using Molecular Oxygen. And the article contained the following:
A copper-catalyzed process for the synthesis of substituted quinazolines from benzonitriles and 2-ethynylanilines using mol. oxygen (O2) as sole oxidant is described. The mild catalytic system enabled the effective cleavage of the C-C triple bond and construction of new C-N and C-C bonds in one operation. Furthermore, the compound N,N-dimethyl-4-(2-(4-(trifluoromethyl)phenyl)quinazolin-4-yl)aniline (3dj) exhibited obvious aggregation-induced emission phenomenon, and the fluorescence quantum yield (ΦF,film) and lifetime (τfilm) were measured to be 45.5% and 5.8 ns in thin films state, resp. The experimental process involved the reaction of 2-((4-Methoxyphenyl)ethynyl)aniline(cas: 157869-15-3).Product Details of 157869-15-3
