SELECTIVE PREPARATION OF α,α-DICHLOROKETONES WITH COPPER(II) CHLORIDE
摘要:
Aryl and enolizable alkyl ketones react with copper(H) chloride in dimethylformamide to produce the corresponding alpha,alpha-dichloroketone in high yields. Remarkable qualities of the process are high selectivity towards these substrates, undetected polychlorinated by-products, easy work-up, commercially available reagents and HCl as the only waste stream.
