REFERENCES

• Stable source of phosphine-free Pd(0), useful in a variety of coupling reactions. Literature references to the use of either "Pd(dba)₂"or "Pd₂(dba)₃" can normally be regarded as interchangeable since the catalyst is of somewhat variable composition depending on the exact method of preparation.
