Abstract: Bis(3-nitrophenoxy) derivatives of aromatic or bridged aromatic hydrocarbons are derived from m-dinitrobenzene and dihydroxy derivatives of said hydrocarbons by a condensation reaction in dipolar aprotic solvents in the presence of bases. The bis(3-nitrophenoxy) derivatives obtained are successively reduced to afford bis-(3-aminophenoxy) derivatives. This is a new method for reacting the dihydroxy-derivatives with m-dinitrobenzene, and hence can prepare novel bis(3-aminophenoxy) derivatives such as 4,4 min -bis(3-aminophenoxy)biphenyl, 1-[4-(3-aminophenoxy)phenyl]-1,3,3-trimethyl-6-(3-aminophenoxy)indan, 6,6 min -bis(3-aminophenoxy)-3,3,3 min ,3 min -tetramethyl-1,1 min spirobiindan, and methyl substituted 2,2 min -bis[4-(3-aminophenoxy)phenyl]propane.

Abstract: The invention relates to a process for the preparation of 4,4'-dichlorodiphenyl sulphone, in which chlorobenzene is reacted with chlorosulphonic acid in a halogenated aliphatic hydrocarbon solvent in the presence of an alkali metal salt of an inorganic or mineral acid and/or an ammonium salt of an inorganic or mineral acid, the reaction mixture formed is washed with water, the organic solvent phase is separated, and water together with the organic solvent is distilled off so as to obtain 4-chlorobenzenesulphonyl chloride in an anhydrous state, and this is then reacted with chlorobenzene in the presence of a catalytic amount of iron(III) chloride to give 4,4'-dichlorodiphenyl sulphone.
