Kind Code:
A1
Abstract:
The present invention provides a catalyst modified by a phosphine ligand, and a preparation method and an application of the catalyst. The preparation method in the present invention uses a phosphine ligand M to modify Pd4S or Pd4S/X to prepare an M-Pd4S catalyst or an M-Pd4S/X catalyst having a carrier.
