Abstract:
1. A method for producing an onium salt derivative, characterized by comprising reacting an onium salt which has a halide Q as an anion moiety and which is represented by any one of formulas (3) or (4): wherein each of R 1 , R 2 , R 3 , and R 5 represents an alkyl group, a cycloalkyl group, a perfluoroalkyl group, an aromatic organic group, an aralkyl group, or a phenacyl group, each of these groups having ≦25 carbon atoms and being optionally substituted; one or both of the pairs of R 1 and R 3 , and R 2 and R 5 may together form a divalent organic group; R 4 represents a C≦20 divalent organic group; and Q represents a halide anion, with an ester compound which has an alkyl group R wherein R 6 represents an alkyl group, a cycloalkyl group, a perfluoroalkyl group, an aromatic organic group, or an aralkyl group, each of these groups having ≦25 carbon atoms and being optionally substituted; R 7 represents an alkyl group, having ≦5 carbon atoms and being optionally substituted; to thereby form R
