Abstract
A bidentate phosphite ligand comprises a backbone having a structure of acenaphthene-1,2-diol in which the hydrogen atoms of the hydroxyl groups have each been replaced by a P(OR1)2 group, where R1 is an aryl radical. When combined with a transition metal, such as nickel, the ligand provides a catalyst complex useful in hydrocyanation and other reactions.
Claims18
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 a bidentate phosphite ligand and at least one transition metal, wherein the bidentate phosphite ligand comprises a backbone having a structure of acenaphthene-1,2-diol in which the hydrogen atoms of the hydroxyl groups have each been replaced by a P(OR1)2 group, wherein R1 is an aryl radical optionally substituted with methyl.
A process for double bond isomerization of an unsaturated compound having no more than one carbon-carbon double bond comprising contacting the compound with a catalyst complex comprising a bidentate phosphite ligand and at least one transition metal, wherein the bidentate phosphite ligand comprises a backbone having a structure of acenaphthene-1,2-diol in which the hydrogen atoms of the hydroxyl groups have each been replaced by a P(OR1)2 group, wherein R1 is an aryl radical optionally substituted with methyl.
A bidentate phosphite ligand comprising a backbone having a structure of acenaphthene-1,2-diol in which the hydrogen atoms of the hydroxyl groups have each been replaced by a P(OR1)2 group, wherein R1 is an aryl radical optionally substituted with methyl.
