| | METHYL OXALYL CHLORIDE Usage And Synthesis |
| 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.
| | Chemical Properties | CLEAR LIQUID | | Uses | Methyl oxalyl chloride is used as a synthetic reagent. It serves as a reagent in the synthesis of fused coumarins, substituted isoxazoles and heterocycles. Further, it is used in intramolecular Wittig reactions, and iron-mediated cleavage of C-C bonds. | | Uses | Reactant involved in:
- Regioselective synthesis of fused coumarins
- Cyclization to form substituted isoxazoles and heterocycles
- Intramolecular Wittig reactions
- Silyl enol ether acylation
- Iron-mediated cleavage of C-C bonds
