摘要： An aromatic compound having sulfonyl groups, as an intermediate or raw material of polyimides having a good and well-balanced heat resistance and moldability is effectively produced by reacting a compound represented by the general formula,R--Ar--Rwherein Ar is ##STR1## Y is a bond, oxygen atom, sulfur atom, SO.sub.2, CH.sub.2 or ##STR2## and R is a hydrogen atom or --SO.sub.2 X and X is a halogen atom or alkali metal, with a compound represented by the following general formula, ##STR3## wherein X.sup.1 and X.sup.2 are simultaneously methyl groups or form ##STR4## and Z is a hydrogen atom, alkyl group having 1 to 6 carbon atoms or aryl group having 6 to 8 carbon atoms and R.sup.1 is a hydrogen atom, --SO.sub.2 X, halogen atom or nitro group, X is a halogen atom or alkali metal and R and R.sup.1 are not same simultaneously, either of which contains --SO.sub.2 X group as a necessary group.
