摘要

Abstract: Rates and heats of reaction are reported for the C-alkylation of alkali salts of various symmetrical 6-diketones with methyl and ethyl iodide in dimethyl sulfoxide (Me2SO). Product analysis by FT-NMR established that the reactions were clean over the concentration range of the kinetic and thermochemical study and, with only one exception, gave 100% carbon alkylation within the limits of detection. The effects of ion pairing, ...
