Abstract
A ligand which contains arsenic and has the formula (I): where n is 2 and the ligand is bidentate; each X is O or NH; and Ar1 and Ar2 may be the same or different and each is an aryl group, provided that each Ar1 group connected to the same As atom may be combined to form a single aryl 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 ligand containing arsenic and having the formula (I):
- wherein
- n is 1 and the ligand is monodentate or n is 2 and the ligand is bidentate,
- each X is O or NH, and
- Ar1 and Ar2 is the same or different and each is an aryl group, and each Ar1 group connected to the same As atom are separate aryl groups or are combined to form a single aryl group.
A process for double bond isomerization of a monoethylenically unsaturated compound comprising contacting said compound with a catalyst complex comprising at least one transition metal and a ligand containing arsenic and having the formula (I):
- wherein
- n is 1 and the ligand is monodentate or n is 2 and the ligand is bidentate,
- each X is O or NH, and
- Ar1 and Ar2 are the same or different and each is an aryl group, and each Ar1 group connected to the same As atom are separate aryl groups or are combined to form a single aryl group.
A ligand containing arsenic and having the formula (I):
- wherein
- n is 2 and the ligand is bidentate,
- each X is O or NH, and
- Ar1 and Ar2 are the same or different and each is an aryl group, and each Ar1 group connected to the same As atom are separate aryl groups or are combined to form a single aryl group.
