CA 2382166
Hydrocyanation reactions employing multidentate phosphite ligands and multidentate phosphite ligands are disclosed. The ligands have phenyl containing substituents attached to the ortho position of the terminal phenol group and/or attached to the ortho position of the bridging group. Catalyst compositions having such ligands achieve 97 % or greater distribution in hydrocyanation.
L'invention concerne des réactions d'hydrocyanation utilisant des ligands de phosphite polydentés, et les ligands de phosphite polydentés eux-mêmes. Ces ligands comportent des substituants phénylés reliés en position ortho du groupe phénol terminal et/ou reliés en position ortho du groupe de pontage. Les compositions catalytiques renfermant ces ligands permettent d'obtenir, par l'hydrocyanation, une distribution supérieure ou égale à 97 %.
