Allyl chloroformate, CH2CI2, >80% yield." In this case, the benzylamine was converted to an alloc carbamate. 

Allyl carbonate esters are also useful hydroxy-protecting groups and are introduced using allyl chloroformate. A number of Pd-based catalysts for allylic deprotection have been developed.209 They are based on a catalytic cycle in which Pd° reacts by oxidative addition and activates the allylic bond to nucleophilic substitution. Various nucleophiles are effective, including dimedone,210 pentane-2,4-dione,211 and amines.212... 

Allyl chloroformate (6 mL) was added slowly, keeping the temperature between 0 and 5 °C. 

Copolymers offer the twin advantages of reduced crystalline melting temperature and introduction of crosslinking sites. One of the best for. both of these purposes that has been reported so far is the thiocarbonyl fluoride-allyl chloro-formate copolymer (39). Products containing as little as 2-3 mole % of allyl chloroformate melt below 0°C and are readily crosslinked by incorporation of zinc oxide followed by heating.

To a solution of 1-O-terr-butyl aspartate [44] (3 g, 15.9 mmol) and KHC03 (3 g, 32 mmol) in water (50 mL) was added at 0°C allyl chloroformate (1.7 ml, 16 mmol E. Merck, Darmstadt, Germany). After stirring for 1 h, the mixture was extracted with diethyl ether (100 mL). The aqueous layer was acidified to pH 2 using 1M HC1 and extracted with diethyl ether (4 x 50 mL). These ether solutions were combined, dried with MgS04. The solvent was evaporated in vacuo to give 34 as an oil 3.87 g (89%), [a]D +21° (c 1, CH2CI2) Rf 0.25 (petroleum ether-ethyl acetate 2 1).
