一般說明

(S)-tBuPHOX-Pd-MAH is a chiral Pd(0) precatalyst first produced in the group of David C. Leitch for asymmetric allylic alkylation reactions. The complex bears a chiral Pfaltz-Helmchen-Williams (PHOX) ligand as well as an easily diplaced maleic anhydride (MAH) ligand.

特點和優勢

(S)-tBuPHOX-Pd-MAH is a rare example of a chiral, isolable Pd(0) precatalyst for allylic alkylation reactions. Using a chiral single-component precatalyst instead of forming the chiral catalytic speices in-situ avoids activity, reproducibility, and/or selectivity problems arising from incomplete formation of the desired chiral catalyst.
