Abstract
Abstract Benzyl phenyl ketones undergo triarylation upon treatment with excess aryl bromides in the presence of a catalytic amount of ce:simple-parad(PPh 3 ) 4 and Cs 2 CO 3 as base in o -xylene on the α- and two ortho -positions of the carbonyl group to give diphenymethyl 2,6-diphenylphenyl ketone derivatives as the predominant products. Acetophenone and diphenylmethyl phenyl ketone similarly undergo tetra- and diarylations, respectively.
