Abstract: 1-Nitroanthraquinone-2-carboxylic acid of the formula I (I) is prepared by treating novel 2-substituted 1-nitroanthraquinones of the general formula II (II) where R is -CH=CH-R1 or -CH2-CHO, where R1 is C1-C5-dialkylamino or a cyclic 5- or 6-membered amine which may contain further hetero atoms, with oxidizing agents free of heavy metal.

Abstract: Prepn. of 2,6- and 2,7-di-t.Bu-anthracene (I) by anthracene (II) alkylation in presence of an acid is effected by (i) reacting (II) with a t.Bu halide or isobutene in a non-polar, aprotic solvent in presence of an acid catalyst; (ii) removing the catalyst and ppted. 2,6-(I) opt. after cooling; and (iii) isolating the 2,7-(I) isomer from the mother liquor. ADVANTAGE - The isomers are obtd. separately in direct fashion without the difficulties associated with the prior-art method of J. Gen. Chem USSR, 22, (1986) p527-31. Also the catalyst can be recyled. In an example, dropwise addn. over 3-4 hrs. of 1.2 mols. t-BuCl to a mixt. of 89g (0.5 mol.) (II), 0.03 mol. AlCl3 and 300 ml CCl4 at 65-67 deg.C, followed by hot filtering to remove the catalyst, recovering the 2,6-isomer, and recrystallising the remaining mother liquor from 500ml EtOH to give the 2,7-isomer resulted in a 60.7g(41%) yield of 2,6-isomer(99% content) and a 58.3g(35%) yield of 2,7-isomer(87% content)
