Abstract
Provided is an optimized process for the synthesis of palladium(0) phosphine complexes. The process described herein is characterized by a more efficient reaction control, high yield and purity, the use of readily available starting materials, and savings in reaction time and steps, thereby offering increased sustainability when compared to processes reported in the state of the art.
Claims30
A process for synthesizing a palladium(0) phosphine complex, wherein said process comprises the following steps:
- (a) reacting a palladium(II) compound with about 3 or more equivalents of a phosphine ligand to obtain a palladium(0) phosphine complex, wherein the equivalents are based on the amount of palladium(II);
- and
- (b) in situ purification of the palladium(0) phosphine complex obtained in step (a).
