Abstract
Fluoride-free cross-coupling reactions of alkenyltrialkoxysilanes with aryl iodides, bromides, and chlorides are performed on water using sodium hydroxide as activator at 120° C under normal or microwave heating. This process occurs in the presence of Pd (OAc) 2 or 4- hydroxyacetophenone oxime-derived palladacycle 1 as precatalysts under ligand-free conditions with low Pd loadings (0.01-1 mol%) and using tetra-n-butylammonium bromide ...
