✦ Synopsis

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 nitro, cyano, ester, and carbonyl groups.
