Abstract
Process for the quantitative preparation of esters, with a high yield, which comprises reacting an aldehyde or ketone compound and an acid halide compound in a one pot reaction in the presence of at least one compound represented by the following formulae: EQU RMgX (I); EQU RMgX/CuX (II); and EQU RLi or R(CuLi).sub.1/2 (III); in which R represents a hydrocarbon group, and X represents a halogen atom. Production processes of a resist material and a semiconductor device are also disclosed.
