- Reacts with nucleophiles at bromine with displacement of the malonate anion. Thus it has been used to introduce the ɑ-methylacetic acid unit at a remote position, asin the -alkylation of unsaturated ketones, in which the displaced malonate anion reacts with the initially-formed ɑ-bromo ketone. This process has been termed "transfer alkylation": J. Am. Chem. Soc., 94, 1790 (1972):
