Abstract
1378773 Preparation of anthraquinone compounds IMPERIAL CHEMICAL INDUSTRIES Ltd 11 Sept 1972 [11 Oct 1971] 47192/71 Heading C4P Anthraquinone compounds of the formula where X is OH or NH 2 , and R<SP>1</SP> and R<SP>2</SP> are H, Cl, Br, C 1 -C 4 alkyl or alkoxy, are prepared by subjecting a di-(boro-C 1 -C 4 alkyl carbonyloxy) complex of a compound of formula to the action of Cl 2 in oleum at -10-100‹ C. and thereafter hydrolysing off the boro-C 1 -C 4 alkylcarbonyloxy groups. The process may be carried out by passing Cl 2 through a solution of the said complex in oleum while stirring, and pouring the reaction mixture on to a mixture of ice and water to effect hydrolysis. A chlorination catalyst, such as iodine, may be present in the reaction medium. The compounds may be used as disperse dyes or as intermediates. The di-(boroalkylcarbonyloxy) complexes may be obtained by adding boric acid to the appropriate acid anhydride at 120‹ C., cooling and adding the anthraquinone compound, heating to 100‹ C. and cooling to 0‹ C. to isolate the complex. When chlorination takes place at below 30‹ C. then hydrolysis of the di-(boro-C 1 -C 4 alkylcarbonyloxy)-complexes gives compounds of the general formula
