    Abstract: In a process for producing n-butylalkyl ethers, (a) 1,3-butadiene or a butadiene-containing hydrocarbon mixture is reacted with an alcohol of formula ROH (I), in which the radical R is a C2-C20 alkyl or alkenyl group substituted or not with 1 to 2 C1-C10 alkoxy or hydroxy groups, a C6-C10 aryl or C7-C11 aralkyl group or a methyl group, at an increased temperature and pressure in the presence of a Brönsted acid or in the presence of a complex of an element of groups Ib, VIIb or VIIIb of the periodic table of elements with a phosphorus- or nitrogen-containing ligand, yielding a mixture of addition products of formulas (II) and (III); (b) the isomers are separated; (c) addition product III is isomerised into addition product II; (d) addition product II is hydrogenated in the presence of a homogeneous or heterogeneous transition metal element catalyst in the liquid phase or in the presence of a heterogeneous, transition metal element-containing catalyst in the gas phase, yielding n-butylalkyl ether of formula (IV).

    Abstract: The invention relates to a catalyst comprising at least one metal complex of the VIII subgroup, which includes at least one monodentate, bidentate or polydentate phosphine amidite ligand of general formula I.1, I.2 and/or I.3, wherein A , together with the phosphorus and the oxygen atoms to which it is bonded, represents a five to eight-membered heterocycle; X represents a five to eight-membered heterocycle having at least one nitrogen atom directly bonded to the phosphorous atom and B represents either a carbon-carbon single bond or a bivalent bridging group. The invention also relates to a method for hydroformylation and hydrocyanation of compounds containing at least one ethylinically unsaturated double bond in the presence of said catalyst.

    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 .
