Ruan, Zhixiong published the artcileRuthenium(II)-Catalyzed meta C-H Mono- and Difluoromethylations by Phosphine/Carboxylate Cooperation, Recommanded Product: Ethylbromofluoroacetate, the publication is Angewandte Chemie, International Edition (2017), 56(8), 2045-2049, database is CAplus and MEDLINE.
Ruthenium(II)-catalyzed meta-selective C-H (di)fluoromethylation was accomplished by phosphine and carboxylate cooperation. The remote C-H functionalization was characterized by ample substrate scope, thereby setting the stage for meta-(di)fluoromethylation through facile C-H cleavage. Thus, 2-phenylpyridine reacted withBrCF2CO2Et in the presence of ruthenium catalyst I and phosphine P(C6H4CF3-4)3 to give pyridinyldifluoroacetate II in 71% yield.
