The methylene group of Benzy Methy Ketone CAS 20320-59-6 BMK is affected by two carbonyl groups and has higher activity. It reacts with sodium ethoxide to generate sodium salt, and then reacts with halogenated hydrocarbons to generate diethyl malonate substituted by monovalent or divalent hydrocarbon groups. They are all important intermediates in organic synthesis, for example, they can be further hydrolyzed and decarboxylated to form carboxylic acids:
In the formula, R and R' are hydrocarbon groups. Benzy Methy Ketone CAS 20320-59-6 can carry out nitrosation reaction and further reduce to produce diethyl aminomalonate, which is an important intermediate for the synthesis of amino acids.
