Abstract:
An acylating agent being composed of(A) a compound represented by the following formula (2a): â€ƒwherein each of Ra1 and Rb1 is, identical to or different from each other, an alkyl group having 1 to 4 carbon atoms, a cycloalkyl group, or an aryl group, or Ra1 and Rb1 when taken together form a cyclopentyl or cyclohexyl ring with the adjacent two carbon atoms to which they are attached; and each of Z1 and Z2 is, identical to or different from each other, an oxygen atom or a hydroxyl group, (B) oxygen, and (C) at least one compound selected from (C1) a metallic compound selected from the group consisting of an elementary metal, a metallic hydroxide, a metallic oxide, a metallic halide, a metallic salt of an oxo acid, an oxo acid containing a metal, an isopolyacid containing a metal, a heteropolyacid containing a metal, a metallic salt of an organic acid, and a metallic complex and (C2) an imide compound represented by the following formula (1): â€ƒwherein each of R1 and R2 is, identical to or different from each other, a hydrogen atom, a halogen atom, an alkyl group, an aryl group, a cycloalkyl group, a hydroxyl group, an alkoxy group, a carboxyl group, an alkoxycarbonyl group, or an acyl group, and R1 and R2 when taken together form a double bond, or a 5- to 12-membered aromatic or nonaromatic ring; X is an oxygen atom or a hydroxyl group; and one or two N-substituted cyclic imido groups indicated in the formula (1) may be bonded to the aforementioned R1, R2, or to the double bond or aromatic or nonaromatic ring formed together by R1 and R2.
