| titleOfInvention | Preparation of phosphine ligands |
| abstract | A process for the preparation of a compound having the formulawherein Ar is an aryl group bearing the PR3R4 and COX groups in a 1,2-relationship, and optionally bearing also one or more non-interfering groups, R3 and R4 are each a hydrocarbon group optionally substituted by any non-interfering group, and X is OH or a non-interfering group, comprises (i) the reaction of NaPR3R4 with F-Ar-COX, or (ii) when X is an amine group, the reaction of R3R4P-Ar-COOY, OY being OH or a leaving group, with a solution of the amine obtained in situ by adding a base to a salt thereof.Certain ligands prepared by such a process are in a novel, crystalline form. |
