C-S Cross-Coupling Reaction Using a Recyclable Palladium Prolinate Catalyst under Mild and Green Conditions

A simple, efficient and green methodology for the C−S cross-coupling reaction using Pd(L-Pro)2 as a heterogeneous catalyst was developed involving aryl iodides, thiols, green-solvent and a low catalytic loading of palladium prolinate. In addition, the catalyst turned out to be recyclable and the products were obtained in good to excellent yields.
