Palladium-catalyzed cross-coupling of 2-iodobiphenyls with ortho-chloroacetophenones through dual C–H arylation for the construction of tribenzo[a,c,f]cyclooctanones

A Pd-catalyzed cross-coupling reaction of 2-iodobiphenyls with ortho -chloroacetophenones has been developed through C–H activation. The reaction provides a straightforward method for the construction of tribenzo[ a , c , f ]cyclooctanones.
