[reaction: see text] Aryltriazenes are directly coupled with areneboronic acids in the presence of a catalytic amount of Pd(2)(dba)(3) and P(tBu)(3) together with 1 equiv of BF(3).OEt(2) in DME to afford the corresponding biaryl products in up to 98% yield. A carbonylative cross-couplingreaction under a carbon monoxide atmosphere is also found to give the corresponding diaryl ketone with a similar
