    Abstract: Primary amines of the antraquinone series are made by allowing strong sulphuric acid, oleum, chlorosulphonic acid or a melt of aluminium chloride and a melting point depressant to act on a cyclohexylamino-anthraquinone which may be substituted in the anthraquinonyl radical. When sulphuric acid or oleum is used, nitrile or amido groups may be wholly or partly saponified or sulphonic acid groups may be introduced. Preferably the acid reagent is a mixture of aluminium chloride and a compound having the general formula X1COX2 in which X1 denotes hydrogen, halogen, alkyl or amino, and X2 denotes an unsubstituted, mono-allyl- or diallyl-substituted amino group, or, if X1 is hydrogen, an O-metal group, or X1 and X2 when taken together denote an alkylenamino or an a ,o -diamino alkylene radical with 3 to 6 methylene groups which together with the CO group form an inner amide, the amido nitrogen of which may be substituted with an alkyl group. Detailed examples are given in which the products contain chloro, sulphonic acid, cyano, methoxy, carboxylic acid cyclohexylamide, carboxylic acid, hydroxy, or carboxylic amide radicals in addition to amino groups.

    Abstract: Compounds of formula wherein X and X1 are F, Cl or Br, Y is H, Cl, Br, Me or Et, Z is H, Cl or Br and R is HO- or a single bond connected to the 3-position of the benzene nucleus, are produced by heating gamma-butyrolactone with at least a molar amount each of a 1,4-dihalobenzene and anhydrous AlCl3, at a temperature from the melting-point of the 1,4-dihalobenzene to 150 DEG C. The 1,4-dihalobenzene may be 1,4-dichlorobenzene (a); 1,4-dibromobenzene (b); 1,4-fluorochlorobenzene (c); 1,2,4-trichlorobenzene; 2,5 - dichlorofluorobenzene; 1,2,3,4 - tetrachlorobenzene; 2,5-dichlorotoluene or 2,5-dichloroethylbenzene. The examples describe the production of beta-(2,5)-dichlorophenyl)-butyric acid and 4,7-dichloro-1-methylindan-3-one from (a); 4,7-dibromo-1-methylindan-3-one from (b); and beta-(2,5-chlorofluorophenyl)-butyric acid and 4,7-fluorochloro-1-methyl-indan-3-one from (c).
