Anwendungen

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. It is a reactant involved in nucleophilic substitution reactions with nitro(pentafluorosulfanyl)benzenes, 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 and addition reactions for syntehsis of enantiopure 3,4-diamino esters or amides.

Bemerkungen

Store at room temperature. Incompatible with oxidizing agents. Ensure proper ventilation.
