The synthesis of selenium and tellurium core-modified carbaporphyrinogens was carried out by the reaction of functional selenophene/tellurophene diols with azulene or a benzitripyrrane in the presence of acid. The products were obtained in moderate yields and were characterized by using 1H and 13C NMR, UV–vis, FT-IR, CV, and HRMS spectroscopic techniques. Further, oxidation of the obtained core-modified
硒和碲核心修饰的碳卟啉原的合成是在酸存在下,通过功能性硒烯/碲代二醇与和苯并三苯并吡喃反应进行的。产品以中等收率获得,并通过1 H和13 C NMR,UV-vis,FT-IR,CV和HRMS光谱技术进行了表征。此外,在DDQ存在下于CHCl 3中氧化获得的核心修饰的碳卟啉原,以良好的收率得到相应的碳卟啉。如通过使用质子NMR光谱法所证实的那样,苯并卟啉没有显示出环电流或大环芳族的迹象,但是TFA的加入引起了弱亲核指示的形成。
