摘要：

A convenient method for the unambiguous preparation of alpha,alpha'-dihalogeno ketones 3 from in situgenerated chloromethyllithium and alpha-chloro or alpha-bromo carboxylic acid esters 1 at -78-degrees-C, is described. The unambiguous preparation of alpha,alpha,-dihalogeno ketones 7 by using in situ-generated dihalogenomethyllithium and carboxylic acid esters 5 at -78-degrees-C is also reported.
