METHOD OF PRODUCING NITRILE COMPOUNDS FROM ETHYLENICALLY UNSATURATED COMPOUNDS Russian patent published in 2014 - IPC C07C253/10 C07C255/01 

FIELD: chemistry.

SUBSTANCE: invention relates to a method for hydrocyanation of ethylenically unsaturated organic compounds containing at least one nitrile group, and can be used in chemical industry. The disclosed method includes performing hydrocyanation by reaction in a liquid medium with hydrocyanic acid in the presence of a catalyst containing a transition metal and an organophosphorus ligand of formula or where R₇ is a divalent radical of general formula (III), and R₉ and R₁₀ denote an aliphatic radical containing 1-6 carbon atoms, R₁, R₂, R₃, R₄ denote a hydrogen atom, an alkyl radical having 1-12 carbon atoms, which may contain heteroatoms; an aromatic or cycloaliphatic radical which may contain heteroatoms; a carbonyl, alkoxycarbonyl or alkoxy radical; a halogen atom, a nitrile group or a haloalkyl group containing 1-12 carbon atoms, X denotes fluorine or bromine.

EFFECT: novel efficient hydrocyanation method which also enables isomerisation of the obtained product.
