A new biarylphosphine ligand, Me(3)(OMe)tBuXPhos (L3), was designed as a surrogate for Me(4)tBuXPhos (L1). The Me(3)(OMe)tBuXPhos could be prepared in a chromatography-free manner from inexpensive and readily available 2,3,6-trimethylphenol. Comparative studies demonstrated that a catalyst based on Me(3)(OMe)tBuXPhos displayed the
