The reaction of aromatic ketones with bis(trichloromethyl) carbonate afforded aryl-(Z)-vinyl chlorides in the presence of scandium triflate, DMF, and benzoyl chloride as catalysts. A plausible addition-elimination mechanism is proposed. This catalytic method enables a green route to aryl-(Z)-vinyl chlorides.
