- A Convenient New Route to 1-Haloalkyl Carbonates
-
Alkyl (or alkenyl or aryl) 1-haloalkyl carbonates are conveniently prepared by reaction of an aldehyde with an alkyl (or alkenyl or aryl) carbonohalidate (haloformate) in the presence of a catalyst.

- Novel Preparation of N-Protected Amino Acid Active Esters Using 1,2,2,2-Tetrachloroethyl Carbonates
-
1,2,2,2-Tetrachloroethyl chloroformate reacts with substituted phenols or N-hydroxy imides to yield crystalline and stable mixed aryl or oximido tetrachloroethyl carbonates.When allowed to react with an N-protected amino acid derivative, these compounds proved to be efficient for the syntheses of the corresponding active esters.A series of active esters including p-nitrophenol, trichlorophenol, pentafluorophenol, and N-hydroxysuccinimide derivatives were prepared by this new procedure.
