Abstract: Prepn. of o-benzyltoluenes (I) by condens. of (II) with (III) (where R1, same or different, is H or halogen; R2 is as R1 or an aliphatic or aromatic radical) in the presence of H2SO4 or a mixt. of H3PO4 and an org. sulphonic acid RSO3H, opt. with cpds. contg. Zn, Sn, or B. Method is less hazardous, gives good yields without need if complicated catalysts, and shows consistent results. Cpds. (I) are inters. e.g. for dyestuffs.

Abstract: Acids of formula (I) (where X and Y are halogen and one of X and Y can also be H) are produced in good yields and in pure form by oxidizing halo-indanes of formula (II) (where R1 and R3 are H or alkyl and R2 is alkyl) with HNO3 at 50-250 degrees C. (I) (of which those compounds in which both X and Y are halogen and Y is ortho or meta to the carbonyl group are new and claimed compounds) are useful as intermediates, esp. for anthraquinones useful e.g. as dyestuffs, as well as for subst. benzanthrones. Peroxides of (I) are useful as initiators for polymerization processes.

Abstract: 1-Nitroanthraquinone is obtd. in up to 80% yield and 85-96% purity, suitable for prepn. of 1-aminoanthraquinone which is sufficiently pure for dye- and dye-precursor mfr., by nitration of anthraquinone, in the presence of >=1 mole 1-4 C perfluoroalkanesulphonic acid, pref. CF3CH2SO3H, for each mole of anthraquinone, and in solvents and diluents which are at least partly miscible with HNO3 and which do not react (undesirably) with the reagents under the reaction conditions, pref. CH2Cl2, CHCl3, CHCl2CH3, CH2ClCH2Cl, CHCl2CHCl2 and/or C3H4Cl2.96-100 wt.% HNO3 is pref. used, in 1-2.5:1, pref. 1.3-1.8:1 molar ratio w.r.t. anthraquinone.

Abstract: Aminobenzonitriles of formula (I): (where X is H, Cl, Br, NO2, CN, Me- or Et-sulphonyl, -COOMe or -COOEt; Y is H, Cl, Br, NO2, CN, Me- or Et sulphonyl, -COOMe or -COOEt, Me, MeO or a gp. of formula: (where R is 1 - 4C alkyl, or Ph opt. substd. by Cl, Br, Me, MeO or EtO; R2 is Me, Et or Ph opt. substd. by Cl, Br or Me; R3 is H, Me or, for Y=Me, 2 - 5C carboxylate, and R2 and R3 together with C atoms linking them form a condensed benzene ring opt. substd. by MeO, EtO, Cl or Me) are prepd. by reacting cpds. (II) (where Hal is Cl or Br and R' is opt. substd. Ph), in solvents with metal cyanides, esp. CuCN or CuCN-forming cpds., to exchange Hal for CN, followed by decompsn. of reaction products to (I) and phosphine oxides.
