Ruthenium-catalyzed
C–H arylation of aromatic nitriles with
arylboronates is described. The use of RuH2(CO){P(4-MeC6H4)3}3 as a catalyst provided
higher yields of the ortho arylation products than the conventional
RuH2(CO)(PPh3)3 catalyst. The arylation
takes place mostly at the ortho positions, but unprecedented para
arylation was also partially observed to give ortho,para diarylation
products. In addition to C–H bond cleavage, the cyano group
was also found to function as a directing group for cleavage of C–O
bonds in aryl ethers.
