ABSTRACT:
Provided is an industrially safe and useful azodicarboxylic acid bis(2-alkoxyethyl) ester compound that is useful for the Mitsunobu reaction in which it is used in combination with a phosphorus compound to carry out a dehydration condensation reaction, and also useful as an oxidizing agent, and a starting material for various synthetic processes. Also provided are a production intermediate of the above-described compound, and methods for producing these compounds. An azodicarboxylic acid bis(2-alkoxyethyl) ester compound represented by formula (1);wherein A represents an alkyl group having 1 to 10 carbon atoms.
