摘要

Hydrocyanation of ethylenically unsaturated hydrocarbon compounds comprises reaction with hydrogen cyanide in a liquid medium in the presence of a catalyst comprising a transition metal and an organophosphorus ligand (I). Hydrocyanation of ethylenically unsaturated hydrocarbon compounds comprises reaction with hydrogen cyanide in a liquid medium in the presence of a catalyst comprising a transition metal and an organophosphorus ligand of formula (I): X1, X2 = O or NR2; R2 = H, alkyl, aryl, sulfonyl, cycloalkyl or a carbonyl-containing group; X3 = a bond, O or NR2; R1 = a 1-12C alkyl, aromatic or cycloaliphatic group optionally containing heteroatoms; L = a divalent 1-12C alkyl, aromatic or cycloaliphatic group optionally containing heteroatoms.
