    Abstract: Phosphabenzene compounds of the formula (I)where the radicals R1 to R13 are, independently of one another, hydrogen, COOM, SO3M, NR3X, NR2, OR, COOR or SR (where M=hydrogen, NH4 or alkali metal, X=anion, R=hydrogen or C1-C6-alkyl), or C1-C12-alkyl, C6-C12-aryl, C7-C12-aralkyl, C7-C12-alkaryl or C3-C6-heteroaromatics, where the alkyl, aryl, alkaryl and aralkyl radicals may bear the abovementioned radicals as substituents and two or more of the radicals may be joined to form aliphatic or fused-on rings, where at least one of the radicals R4 and R8 and at least one of the radicals R9 and R13 is not hydrogen, can be used for preparing hydroformylation catalysts.

    Abstract: Preparation of a composition of 9-21C primary alcohol comprises: dimerization of 4-10C monoolefin containing internal and/or terminal double bonds in the presence of an aluminum catalyst (I); hydroformylation of the obtained olefin dimer composition by means of a carbon dioxide/hydrogen mixture in presence of a hydroformylation catalyst, which is homogeneously dissolved in a reaction medium; and catalytic hydrogenation of the obtained aldehyde composition to the corresponding alcohol. Preparation of a composition of 9-21C primary alcohol comprises: catalytic dimerization of 4-10C monoolefin containing internal and/or terminal double bonds; hydroformylation of the obtained olefin dimer composition by means of a carbon dioxide/hydrogen mixture in presence of hydroformylation catalyst, which is homogeneously dissolved in a reaction medium; and catalytic hydrogenation of the obtained aldehyde composition to the corresponding alcohol; where the dimerization is carried out at 160-260[deg]C in the presence of an aluminum catalyst (I) of formula AlRx(ORy)3x, and the hydroformylation is carried out in the presence of a rhodium complex dissolved in the reaction medium with a ligand containing phosphacyclohexane group, free ligand and optionally in the presence of a solvent at 50-250[deg]C and 10-100 bar. R, Ry : 1-10C alkyl; and x : 0-3.

    IPC: C07F9/6568

    Abstract: Preparation of phosphabenzene compounds (A) by reacting the corresponding pyrilium salt (III) with phosphine, optionally in presence of solvent but without addition of acid catalyst or base. (III) and phosphine are contacted at about 0 degrees C then reacted at 0-200 degrees C at pressure over 1 bar. (A) have formulae (I) or (II); R -R = hydrogen, COOM, SO3M, NR3X, NR2, OR, COOR, SR, 1-12C alkyl, 6-12C aryl, 7-12C aralkyl or alkaryl, or 3-6C heterocyclylalkyl with 1-3 heteroatoms, optionally substituted by the above groups, or two or more R groups together form a fused aliphatic ring; M = hydrogen, ammonium or alkali metal; X = anion; R = hydrogen or 1-6C alkyl; W = bridge comprising covalent bond, oxygen, sulfur, amino, di(1-6C)alkylsilyl or 1-16C residue that includes one or more linked cyclic or aromatic nuclei and optionally interrupted by 1-3 heteroatoms, and each o- or m-position on the phosphabenzene ring that is not bound to the bridge may be substituted by R -R .
