A Selective and Benign Synthesis of Functionalized Benzalacetones via Mizoroki-Heck Reaction Using Aryldiazonium Salts

Palladium-catalyzed Mizoroki-Heck reactions were carried out in the presence of calcium carbonate in alcoholic solvents. Under these conditions an efficient preparation of functionalized benzalacetones was developed The reactions were carried out at room temperature and aerobic conditions, giving the products within several minutes in up to 95% isolated yields. Furthermore, some kinetic investigations, mechanistic insights and considerations are presented
