Synthesis of imidate hydrochlorides by reaction of ethyl.
Benzyl chloroformate (CbzCl) (1a) was introduced by Bergmann and Zervas about 70 years ago for a N-protective reagent for amino group in peptide synthesis. 1 Benzyl chloroformate (1a) smoothly reacts with an amino group of amino acids in aqueous solution under weak basic conditions, and the N-protective Cbz group can be removed either by.
Ethyl chloroformate is the ethyl ester of chloroformic acid. It is a reagent used in organic synthesis for the introduction of the ethyl carbamate protecting group and for the formation of carboxylic anhydrides. Safety ( edit ) Ethyl chloroformate is a highly toxic substance.

An efficient, clean and easy high-yielding synthesis of 3,5-disubstituted 1,2,4-oxadiazoles starting from mixed anhydrides (generated from carboxylic acids and ethyl chloroformate) and.
Benzyl chloroformate is the benzyl ester of chloroformic acid. Also known as benzyl chlorocarbonate it is an oily colorless liquid although impure samples appear yellow. It is also known for its pungent odor. In contact with water it degrades.
Phosgene-derived chloroformates and acid chlorides are, by their nature, reactive chemical species and are employed as key building blocks in many diverse downstream applications. These intermediates are used in the manufacture of organic peroxide initiators for use in plastics and in activating groups used to make antibiotics and other pharmaceuticals.

ETHYL CHLOROFORMATE decomposes slowly in water to form ethanol, HCl, and CO2 Attacks many metals especially in humid atmosphere (Handling Chemicals Safely 1980. p. 476). May react vigorously or explosively if mixed with diisopropyl ether or other ethers in the presence of trace amounts of metal salts (J. Haz. Mat., 1981, 4, 291).
