Abstract
The invention relates to a method for producing a benzoic acid derivative represented by the general formula (1). The method includes the step of reacting an aromatic compound represented by the general formula (2), with carbon monoxide and a hydroxy compound (i.e., water or an alcohol), in the presence of (a) a metal compound containing a metal of 8, 9 and 10 groups of periodic table, (b) a first phosphine derivative represented by the general formula (R.sup.1).sub.2 P--Q--P(R.sup.1).sub.2, and (c) a base, ##STR1## It is possible to easily and efficiently produce the benzoic acid derivative by the method.
