• Methyl chloroformate (mcf) is generally used for the derivatization of functional groups such as carboxylic acids, amines, and phenols.mcf can also be used:
• To activate 3-acylpyridines for nucleophilic addition with alkynyltin reagents to form 2,3-disubstituted 1,2-dihydropyridines
• Chloroesterification of terminal alkynes to form α-chloro-α,α-unsaturated esters
• As an electrophilic reagent to mediate the reaction of pyridine with lithium dialkyl- or diarylcuprates to form 4-substituted 1,4-dihydropyridine derivatives
• To convert nitronates into methoxycarbonyl nitronates
