of a mixture of polyhalomethane and a carbonylcompound with a hindered lithium amide. The kinetically controlled, selective lithiation of the halide enables us to avoid a troublesome procedure involving preformed lithiumcarbenoid. The halide components examined are dichloromethane, dibromomethane, diiodomethane, chloroform, and bromoform, while the carbonyl ones are ubiquitous ketones and nonanal
