various ruthenium carbonyl phosphine catalysts for arylation via cleavage of inert aromatic carbon-oxygen bonds. The use of catalyst systems consisting of [RuCl2 (CO)(p-cymene)], CsF, styrene, and phosphines enabled facile screening of phosphine ligands. Asymmetric C-O arylation was also achieved for atropo-enantioselective biaryl synthesis using a chiral monodentate phosphine ligand.
我们在这里报告了一种通过裂解惰性芳香族碳-氧键原位生成各种钌羰基膦催化剂进行芳基化的方法。使用由[RuCl2(CO)(p-cymene)],CsF,苯乙烯和膦组成的催化剂体系,可轻松筛选膦配体。使用手性单齿膦配体还可以实现对映体-对映体选择性联芳基的不对称CO芳基化。
