| Application: | Methyl dichloroacetate may be used: • in the diastereoselctive synthesis of bicyclic chlorocyclopropane • as difunctional initiator during atom transfer radical polymerization of methyl or n-butyl acrylate • as reagent during CrCl2-induced olefination of aldehydes |
| Application: | Reactant involved in: • Nucleophilic substitution reactions with nitro(pentafluorosulfanyl • Azide-alkyl halide cycloaddition and atom transfer radical addition • Chemical modification of STn antigen for enhancement of synthetic carbohydrate vaccines • Three component reaction of arynes with cyclic ethers and active methines • Catalytic radical haloalkylation for synthesis of neodysidenin • Addition reactions for syntehsis of enantiopure 3,4-diamino esters or amides |
| General description: | Methyl dichloroacetate undergoes base-catalyzed condensation with aliphatic α-haloaldehydes. Chlorination of methyl dichloroacetate by using trifluoromethanesulfonyl chloride has been reported. |
