“…Using these phosphites as ligands, catalyst turnover numbers up to 820,000 were obtained even with deactivated aryl bromides and, for the first time, it was shown that the Pdphosphite complex generated in situ also catalyses efficiently the Suzuki reaction of aryl chlorides. 184 Beller et al 185 also demonstrated that the 1,6-diene Pd(0) monophosphine complexes 97-100 ( Figure 16) are extremely efficient catalyst precursors for Suzuki reactions of various aryl chlorides and found that, by variations of both the diene and the phosphine part of the complex, the catalytic properties of these complexes could be tuned. Interestingly, these monophosphine complexes were found to be superior to generally applied mixtures of palladium precatalysts and phosphines.…”
