Tertiary amine-catalyzed reaction of phenyl glycidyl ether and substituted benzoic anhydrides
Tertiary amine-catalyzed reaction of phenyl glycidyl ether and substituted benzoic anhydrides. Tanaka, Yoshio (Res. Inst. Polym. Text., Yokohama, Japan). Sen'i Kobunshi Zairyo Kenkyusho Kenkyu Hokoku, 107, 31-8 (Japanese) 1975. CODEN: SKZHA8. DOCUMENT TYPE: Journal CA Section: 22 (Physical Organic Chemistry) Addn. of ethers (I; R = NO2, H, MeO) to the anhydrides (II; R1 = NO2, Cl, H, Me, MeO), was studied kinetically in the presence of Bu3N in PhNO2 and xylene at 110-40.degree.. The conversions of I and II were obtained by d[I]/dt = -k[amine][I][II], and d[II]/dt = -(k + k'[I])[amine][I][II], resp., where k and k' are rate consts. Electron-withdrawing substituents of I and II increased the reaction rate and the reaction consts. 794-94-5 and 93-97-0 are just another two chemicals used in this study. increased with temp. .
