The cross-coupling reaction of (RO)2BB(OR)2 (XO = methoxo and pinacolato) with aryl triflates to give arylboronates was carried out at 80 \*C. in the presence of PdCl2(dppf) (3 tool%), dppf (3 tool%) and KOAc (3 equivs) in dioxane. The reaction was available wim various functional groups such as nit
The cross-coupling reaction of arylboronic acids (1.3 equivs) with aryl methanesulfonates was carded out in the presence of anickel(O) catalyst(3 tool%) and K3PO~,nH20 (3 equivs). The use of toluene as the solvent and the nickel(O)-dppf catalyst prepared from NiC~(dppf) plus dppf with BuLi were reco
