Methyl oxalyl chloride Use and Manufacturing

Uses

Methyl oxalyl chloride is an important organic intermediate (building block) to synthetize substituted methyl oxalyl products. It can be used for regioselective synthesis of fused coumarins, cyclization to form substituted isoxazoles and heterocycles, intramolecular Wittig reactions, silyl enol ether acylation, and iron-mediated cleavage of C-C bonds.
