To obtain the subject new compound by directly esterifying a (meth) acrylic acid derivative with an alcohol halide in the presence of a 2,6- disubstituted pyridine as a polymerization inhibitor at a temperature of ≤50°C.
A new (meth)acrylic acid ester, e.g. pentafluorophenyl acrylate. The new (meth)acrylate ester is obtained by reacting an alcohol halide such as a compound of formula I [Y is C(Chal3)2 (hal is a halogen); (n) is 0, 1; Z is F, Cl, etc.; (m) is 1-5] with a (meth)acrylic acid derivative of formula II (X is H, CH3, etc.; A is H, hal etc.; A' is the same group as A]. For example, acrylonitrile is dropwisely added to a stirred solution of pentaflurophenol, 2,6- lutidine and DMAP as a catalyst in TFL cooled at 0°C, and the precipitated rutidine hydrochloride is filtered and purified to obtain pentafluorophenyl acrylate (acrylic acid ester 1).
