| abstract | An aromatic group is introduced into the nucleus of an aromatic hydrocarbon by reacting the latter with an aromatic sulphone at elevated temperature in the presence of an alkaline material. The aromatic compound may be benzene, naphthalene, diphenyl, ter- and quaterphenyls, indene or anthracene and may contain an alkyl, cycloalkyl or aryl substituent. The sulphone contains an aromatic group linked by an-SO2-group to another organic, preferably aromatic group. The aromatic radical may be phenyl, tolyl, diphenylyl or naphthyl, and may contain an alkyl or cycloalkyl group. The alkaline material may be an alkali metal hydroxide, sodium or potassium carbonate, or calcium or barium oxide or hydroxide. The aromatic compound is used in excess of the sulphone up to a mol ratio of 25:1. Reaction is effected at 200-400 DEG C., preferably in liquid phase for 2-12 hours.ALSO:An aromatic (including heterocyclic aromatic) group is introduced into the nucleus of an aromatic (including heterocyclic aromatic) compound by reacting the latter with an aromatic sulphone at elevated temperature in the presence of an alkaline material. The aromatic compound may be benzene, naphthalene, furan, thiophene, pyridine, diphenyl, diphenyl ether, (di)benzothiophene, (di)benzofuran, ter- and quater-phenyls, indene, anthracene or quinoline and may contain an alkyl, cycloalkyl or aryl substituent. The sulphone contains an aromatic group linked by an -SO2- group to another organic, preferably aromatic group. The aromatic radical may be phenyl, tolyl, diphenyl, naphthyl, furyl, thienyl, pyridyl, (di)benzothienyl or quinolinyl and may contain an alkyl or cycloalkyl group. The alkaline material may be an alkali metal hydroxide, sodium or potassium carbonate, or calcium or barium oxide or hydroxide. The aromatic compound is used in excess of the sulphone up to a mol ratio of 25:1. Reaction is effected at 200-400 DEG C., preferably in liquid phase for 2-12 hours. |
