Abstract: The invention relates to a method for hydrocyanating an olefinically unsaturated nitrile in the presence of a catalyst that contains Ni(0). The inventive method is characterized in that the reaction is carried out in the presence of a hydrocarbon that, under certain pressure, concentration and temperature conditions, leads to the formation of at least two liquid phases of the overall system of which one phase, with regard to the overall weight of the phase, has a higher proportion of the catalyst containing Ni(0) than the other phase or other phases.

Abstract: New pnicogen compounds (I) comprise two pnicogen (i.e. phosphorus, arsenic or antimony) atoms covalently bonded (optionally via oxygen) to the terminal flanking methylene groups of a bridge having at least 4 bridging atoms and forming part of an alicyclic or aromatic group. Pnicogen compounds of formula (I) are new. R1 - R4 = heteroatom-containing groups bonded to Pn via O or optionally substituted N; or R1 + R2 and/or R3 + R4 = divalent heteroatom-containing group bonded to Pn via two of O and/or optionally substituted N; a, b = 0 or 1; Pn = P, As and Sb; Ra - Rd = H, alkyl, cycloalkyl, heterocycloalkyl, aryl or heteroaryl; Y = divalent bridging group having 2-10 bridging atoms between the terminal bonds, at least two of the bridging atoms being part of an alicyclic or aromatic group. An Independent claim is included for new catalysts (A) comprising at least one complex of a Group VIII transition metal (specifically cobalt, rhodium, ruthenium or iridium) containing at least one compound (I) as ligand.

Abstract: Disclosed is a method for producing aminodihalophosphines, diaminohalophosphines, triaminophosphines, phosphite diamides, aminophosphines, diaminophosphines, phosphite amide halogenides, and aminophosphine halogenides by separating an acid in the presence of an auxiliary base. Said auxiliary base b) forms a salt with an acid, which is liquid at temperatures at which the valuable product is not significantly decomposed during separation of the liquid salt, and c) the salt of the auxiliary base and the valuable product or the solution of the valuable product form two immiscible phases in a suitable solvent.
