WebFeb 12, 2024 · The malonic ester synthesis is a series of reactions which converts an alkyl halide to a carboxylic acid with two additional carbons. One important use of this synthesis pathway is that it allows for the creation of α-alkylated carboxylic acids which cannot be created by direct alkylation. WebAlkylation and dealkylation reactions are characteristics especially for poly[alkylalkylene (arylene) phosphate]s in which the alkyl radical in the side chain is methyl or ethyl (Scheme 2.32). In these reactions, the α-carbon atom of the side alkoxy group plays the role of the electrophilic center.
