Application

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 β-chloro-α,β-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.
