Significance

Ph3P-modified Ru/CeO2 (3Ph3P-Ru/CeO2) was prepared by immobilization of [RuCl2(CO)3]2 onto CeO2 followed by the treatment with Ph3P under hydrogen. The 3Ph3P-Ru/CeO2 composite catalyzed the direct C-H arylation of aromatic compounds 1 with aryl halides 2 to give the corresponding biaryls 3 in 53-98% isolated yield (12 examples).
