Kinetic studies that evaluate the solvolytic mechanisms of allyl and vinyl chloroformate esters.

At 25.0 °C the specific rates of solvolysis for allyl and vinyl chloroformates have been determined in a wide mix of pure and aqueous organic mixtures. In all the solvents studied, vinyl chloroformate was found to react significantly faster than allyl chloroformate.

Correlation of the rates of solvolysis of neopentyl chloroformate-a recommended protecting agent.

The specific rates of solvolysis of neopentyl chloroformate (1) have been determined in 21 pure and binary solvents at 45.0 °C. In most solvents the values are essentially identical to those for ethyl and n-propyl chloroformates.

Extended Grunwald-Winstein analysis - LFER used to gauge solvent effects in p-nitrophenyl chloroformate solvolysis.

Specific rates of solvolysis at 25 degrees C for p-nitrophenyl chloroformate (1) are analyzed using the extended (two-term) Grunwald-Winstein equation. For 39 solvents, the sensitivities (l = 1.68+/-0.
