Abstract
The competition between Heck-type coupling and conjugate addition in phosphine–rhodium catalyzed reactions of aryl boronic acids with α, β-unsaturated carbonyls has been systematically investigated in a toluene–H2O biphasic system. Aside from the intrinsic nature of rhodium and the enolization of carbonyls, the phosphine supporting ligand on rhodium, the ratio of aryl boronic acid to α, β-unsaturated carbonyl and the pH value of the ...
