ORGANOPHOSPHORUS COMPOUNDS, CATALYTIC SYSTEMS INCLUDING SAID COMPOUNDS AND HYDROCYANATION OR HYDROFORMYLATION METHOD USING SAID CATALYTIC SYSTEMS

摘要

The invention relates to organophosphorus compounds, to catalytic systems including a metal element forming a complex with organophosphorus compounds, and to hydrocyanation or hydroformylation methods implemented in the presence of such catalytic systems. The invention relates to organophosphorus compounds of the general formula (I) or (II) in which: R1, R2, R3, R4, R5, R7 and Z are identical or different and are a hydrogen atom, a linear or branched alkyl radical having from 1 to 12 carbon atoms that may contain heteroatoms, a radical including a substituted or unsubstituted aromatic or cycloaliphatic radical that may contain heteroatoms, a carbonyl, alkoxycarbonyl or alkoxy radical, a halogen atom, a nitrile group or a halogenoalkyle group with 1 to 12 carbon atoms; X, X1 and X2 are identical or different and are an oxygen, nitrogen, sulphur, carbon or silicon atom; R6 is a covalent bond, a linear or branched aliphatic radical, a radical including a substituted or unsubstituted aromatic or cycloaliphatic radical or several aromatic cycles condensed or bonded together by a bond; n and ni are identical or different and are integers respectively equal to the valence of the elements X1, X2 minus 2.
