General description

Propargyl chloroformate is a propargyl ester. It serves as a protecting group for the hydroxy and amino functional group. Rates of solvolysis of propargyl chloroformate has been analyzed in various solvents of widely varying nucleophilicity and ionizing power values using the extended Grunwald-Winstein equation.

Application

Propargyl chloroformate may be used for the preparation of the following:

• binaphthol-diacetylene derivatives
• propargyl pentafluorophenyl carbonate
• N-Poc protected amino acids (Poc = propargyloxycarbonyl)
