A ligand free catalytic system consisting of Pd(OAc)2 (cat) and stoichiometric quantities of silver salts, AgOAc or AgBF4, exhibit high efficiency in the Mizoroki‐Heck arylation, transforming aryl iodides and 1,1 as well as 1,2 disubstituted alkenes into 1,1,2 – trisubstituted aryl alkenes in excellent yields in very short reaction times.
由Pd(OAc)2(cat)和化学计量的银盐AgOAc或AgBF 4组成的无配体催化体系在Mizoroki-Heck芳基化反应中表现出高效率,可转化芳基碘化物和1,1以及1,2在非常短的反应时间内,双取代的烯烃就可以以优异的收率转化成1,1,2-三取代的芳基烯烃。
