An Improved Synthesis of BrettPhos- and RockPhos-Type Biarylphosphine Ligands
Improved processes for the preparation of biphenyl-based phosphine ligands t-BuBrettPhos, RockPhos, and BrettPhos are presented. The new methods, featuring the use of Grignard reagents and catalytic amounts of copper, are superior to the previous methods, which require the use of tert-butyllithium a...
