Abstract
The alkylation of ambident enolate anions-obtained from aliphatic ketones (and one particular type of aldehyde)-was studied using various solvents, bases, alkylating agents and substrates. Alkylation with a reactive alkylating agent (dialkyl sulfates, triethyloxonium fluoroborate) in an aprotic polar solvent (e.g., Me2SO) yields mainly enol ethers, the products of alkylation at O. The predominance of alkylation at O over alkylation at C in these fast reactions and the behavior of the various enolate anions are interpreted with the aid of the principle of least motion.
