The title compound, C(15)H(14)O(2), was obtained by Friedel-Crafts acyl-ation between 2,5-dimethyl-phenol and benzoyl chloride in the presence of aluminium chloride as a catalyst. The dihedral angle between the benzene rings is 61.95 (4)°. In the crystal, O-H⋯O hydrogen bonding and C-H⋯O weak inter-actions lead to polymeric C(6), C(8) and C(11) chains along the a, b and c-axis directions, respe...

Edge-selectively grafted graphite (EGG) with poly(ether-ketone) was prepared by the Friedel-Crafts acylation in a mild polyphosphoric acid (PPA)-phosphorous pentoxide (P(2)O(5)) mixture. The homogeneous reaction dope was coagulated in air moisture at different temperatures. The morphology of expanded EGG was changed from balls, balls/rods and rods with respect to coagulation temperatures of 80,...

3- or 4-Aroylfurans have been prepared selectively and in high yields from a common precursor by simple tuning of reaction conditions in Friedel-Crafts acylation promoted by triflic anhydride. The formation of products can be explained on the basis of the ring-chain tautomerism occurring in compounds equipped with two neighbouring carboxylic functions. Since 4-aroylfuran derivatives show a typi...
