Abstract

1431640 Aliphatically unsaturated aromatic amino compounds BAYER AG 17 Dec 1974 [18 Dec 1973 28 May 1974] 54408/74 Heading C2C [Also in Division C1] Aromatic amines wherein the amino group is aromatically bonded and which contain aliphatic C-C multiple bonds are obtained by hydrogenation of aromatic nitro compounds wherein the nitro group is aromatically bonded and which contain aliphatic C-C multiple bonds in the presence of metal sulphides of the formula wherein M is a metal of Group VIII of the Periodic Table or rhenium, and x is 1 to 4, as catalyst, at 20‹ to 140‹ C. and 5 to 150 bars H 2 pressure. The hydrogenation may be carried out in an inert solvent. In nitro compounds to be used as starting materials in this process there may be more than one nitro group and one or more olefinic bonds present; the olefinic bond may occur as an isolated bond in a carbon chain, in or attached to a cycloaliphatic ring, in or attached to a heterocyclic ring or attached to an aromatic ring, and may be in conjugation with a carbonyl, carboxyl, CN, SO 2 or phosphorus group. The group containing the olefinic bond can be bonded directly to the aromatic ring which bears the nitro group, or can be bonded via a -SO 2 -, -O-, -S-, -CO-, -CONH-, -COO-, amino, imino, imide, imino-imide, phenyl or heterocyclic group, and the heterocyclic group or the phenyl group may be fused to the ring which bears the nitro group.
