    Abstract: A process for preparing a substituted aromatic compound, comprising combining an aromatic compound and cuprous (Cu+) ions in a reaction vessel in an essentially oxygen-free environment, and adding to said reaction vessel a source of an electrophile or a nucleophile substituent, to form an aromatic compound product which is ring-substituted with said electrophile or nucleophile at a position which was originally occupied by hydrogen, and isolating the substituted aromatic compound from the reaction mixture.

    Abstract: A process for producing a bis(4-hydroxy-3-nitrophenyl) compound, characterized in that a bis(4-hydroxyphenyl) compound comprising two phenyl groups bonded to each other directly or through an electron-donating bridging group, sulfoxide group, sulfone group, or carbonyl group is nitrated with nitric acid in an inert solvent substantially in the absence of any other acid. By the process, the target compound reduced in the content of trinitro-substituted compounds can be produced in high yield. Recrystallizing the compound easily gives in high yield a high-purity product suitable for use as a raw material for a heat-resistant polymer, etc., because the content of trinitro-substituted compounds in that compound is low.

    Abstract: A solvent free process for the nitration of an aromatic compound using an aluminosilicate catalyst which has been treated with nitric acid and an acid anhydride. The process enables nitrated aromatic compounds to be produced in high yields and with good regioselectivity. The process also avoids the need to recover the nitrated product from large volumes of solvent and avoids treatment of inorganic acid waste, both of which may be undesirable for environmental reasons.
