On July 20, 2022, Liu, Bin; Wang, Guanyu; Xu, Zhenhao; Wang, Menglin; Nie, Yangleiyu; Luo, Zhibin published an article.Reference of 2-Methoxynaphthalene The title of the article was Ionic liquid/boronic acid system enabled deuteration with D2O. And the article contained the following:
The development of transition-metal free systems for multi-sites deuteration is important for the preparation of deuterium-labeled drugs and intermediates e.g, d-agomelatine. The ionic liquid [bmim]PF6, which was able to promote highly efficient deuterodeborylation of boronic acids RB(OH)2 [R = thianthren-1-yl, 1-benzothiophen-2-yl, 4-formyl-2-methoxyphenyl, etc.] with D2O was reported. The ionic liquid/boronic acid system was successfully applied to the selective H/D exchange at various sp2/sp3 C-H positions. Moreover, unusual nucleophilic behaviors of nitrogen-containing heteroaromatics in ionic liquid were observed The experimental process involved the reaction of 2-Methoxynaphthalene(cas: 93-04-9).Reference of 2-Methoxynaphthalene
