Trichloromethyl chloroformate is used as a reagent in the synthesis of organic compounds. It serves as a source of phosgene used in some laboratory preparations. Also, it is used as a reactant for the synthesis of cyclic carbamimidates, N-alkenyl and cycloalkyl carbamates and prostate-specific membrane antigen-targeted anticancer prodrugs. In addition, it is involved in the preparation of an erythromycin A derivatives and antibody-drug conjugates. It is utilized in the conversion of amines, carboxylic acids, formamides in to isocyanates, acid chlorides and isocyanides respectively.
Convenient replacement for phosgene in many reactions, for example:
Conversion of amines to isocyanates: J. Org. Chem., 41, 2070 (1976); Org. Synth. Coll ., 6, 715 (1988). For aliphatic amines, best results were obtained in the presence of the hindered amine 1,8-Bis(dimethylamino)naphthalene, L00313: J. Org. Chem., 61, 3883 (1996).
