Abstract
A bidentate phosphite ligand having the following structure: Formula (I) wherein each R1 group is an alkyl group or an aryl group and the two R1 groups bonded to the same phosphorus atom may be interconnected, wherein, when each R1 group is an alkyl group, the two alkyl groups bonded to the same phosphorous atom are interconnected; and wherein each R2 group is an alkyl group.
Claims20
A process for the hydrocyanation of an organic compound containing at least one olefinic group comprising reacting the organic compound with hydrogen cyanide in the presence of a catalyst complex comprising at least one transition metal and a bidentate phosphite ligand having the following structure:
- wherein
- each R1 group is an alkyl group or an aryl group and the two R1 groups bonded to the same phosphorus atom may be interconnected, and
- each R2 group is an alkyl group.
A process for the isomerization of a monoethylenically unsaturated compound comprising contacting said compound with a catalyst complex comprising at least one transition metal and a bidentate phosphite ligand having the following structure:
- wherein
- each R1 group is an alkyl group or an aryl group and the two R1 groups bonded to the same phosphorus atom may be interconnected, and
- each R2 group is an alkyl group.
A bidentate phosphite ligand having the following structure:
- wherein
- each R1 group is
- an alkyl group and the two R1 groups bonded to the same phosphorus atom are interconnected to form the following structure:
- R1 is a phenyl ring which is optionally substituted with one or more alkyl groups having 1 to 4 carbon atoms, and
- each R2 group is an alkyl group.
