An efficient synthetic route towards previously inaccessible dibenzo[f,h]quinazolines and [1]benzothieno[3,2-f]benzo[h]quinazolines through FeCl3-mediated intramolecular oxidative cyclodehydrogenation of readily available 5-([1,1′-biphenyl]-2-yl)pyrimidines and 5-(2-phenylbenzo[b]thiophen-3-yl)pyrimidines is described. Molecular orbital calculations (DFT), as well as redox and photophysical measurements
向先前无法二苯并[一种有效的合成路线F,H ]喹唑啉和[1]苯并噻吩并[3,2- ˚F ]苯并[ ħ ]通过的FeCl喹唑啉3介导的分子内氧化性的环化脱氢容易获得的5 - ([1,1'描述了-联苯基] -2-基)嘧啶和5-(2-苯基苯并[ b ]噻吩-3-基)嘧啶。已经对所有新化合物进行了分子轨道计算(DFT)以及氧化还原和光物理测量。数据表明,报道的多环系统具有在有机电子应用中使用的潜力。
