Zinc-copper (I) chloride or-silver (I) acetate promoted aldol reaction of chlorodifluoromethyl ketones with carbonyl compounds. A general and effective route to α, α- …
Abstract Chlorodifluoromethyl ketones efficiently underwent the aldol reaction with a variety of aldehydes or ketones in the presence of zinc, a catalytic amount of copper (I) chloride or silver (I) acetate and molecular sieves to give the corresponding α, α-difluoro-β-hydroxy ketones in good to excellent yields.
