Abstract
PURPOSE: To obtain the titled compound useful as a monomer for a heat- resistant polymer or an intermediate for agricultural chemical, drug, etc. easily in high yield, by reacting 4,4'-difluorodiphenylmethane as a raw material with a tetravalent cerium compound.
CONSTITUTION: 4,4'-Difluorodiphenylmethane is reacted with an equimolar amount or more of a cerium (IV) compound in a solvent such nitric acid, sulfuric acid, acetic acid, etc., at 10W300°C for 1minW50hr at normal pressure, to give the aimed compound. A salt with an inorganic acid such as cerium (IV) sulfate, cerium (IV) hydrogensulfate, cerum (IV) nitrate, cerium (IV) iodate, etc., cerium (IV) hydroxide, cerium (IV) oxide, or a double salt such as ammonium cerium (IV) sulfate, ammonum cerium (IV) nitrate, magnesium cerium (IV) magnesium (IV), etc., may be cited as the tetravalent cerium compound.
