Abstract

To our interest, when we studied Ni-catalyzed C−O cleavage of aryl carboxylate to cross couple with boroxine 2a,(8) in the presence of a cyano group on substrate 1, two different coupling products were isolated in comparable yields (Scheme 1). It implied that the same condition not only activated the aryl C−O bond but also induced the cross coupling between arylnitriles and phenylboroxine. This observation also showed the potential ability of aryl boroxine to ...
