Reactivity of some carboxylic acids in reactions with some epoxides in the presence chromium (III) ethanoate

Bukowska, Agnieszka,Bukowski, Wiktor

, p. 234 - 237 (2002)

Reactivities have been compared of acetic, acrylic, and methacrylic acid in reactions with epichlorohydrin, phenylglycidyl ether, glycidyl acetate, and glycidyl methacrylate carried in the presence of chromium (III) ethanoate. The acid reactivities changed differently with respect to the oxirane series. The effect of solvents on the reactions of acids with epichlorohydrin has also been observed.
