Abstract:
A process for producing a diaryl sulfide derivative or a salt thereof by reacting a halogen-substituted phenyl derivative of the general formula (1): ##STR30##(where X is a halogen atom and R.sub.1 -R.sub.5 is any substituent selected from among hydrogen, a lower alkyl group, a lower cycloalkyl group, an aryl group, a halogen atom, a lower alkoxyl group, an amino group, an N-lower acylamino group, a nitro group, a lower alkylthio group and a carboxyl group) with a disulfide derivative of the general formula (2): ##STR31##(where R.sub.6 -R.sub.10 is any substituent selected from among hydrogen, a lower alkyl group, a lower cycloalkyl group, an aryl group, a halogen atom, a lower alkoxyl group, an amino group, an N-lower acylamino group, a nitro group, a lower alkylthio group and a carboxyl group) in the presence of a metal catalyst to form a sulfide bond, thereby producing a diaryl sulfide derivative of the general formula (3): ##STR32##(where R.sub.1 -R.sub.10 are the same as defined above).
