PXPd-catalyzed borylation of aniline derivatives

Addition of pinacolborane (HBO(2)C(2)Me(4)) to 2-iodoaniline can be catalyzed using a number of palladium complexes, including [(t-Bu)(2)PCl](2)PdCl(2) (PXPd), to give the corresponding boronate ester 2-H(2)NC(6)H(4)(BO(2)C(2)Me(4)) in excellent yields. The PXPd system could also be used in the catalyzed borylation of substituted anilines to give the corresponding aminoboronate esters in moderate to high yields.
