WebA palladium‐catalyzed asymmetric synthesis of silicon‐stereogenic 5,10‐dihydrophenazasilines was developed that proceeds via an unprecedented enantioselective 1,5‐palladium migration. High enantioselectivity was achieved by employing 4,4′‐bis(trimethylsilyl) (R)‐Binap as the chiral ligand, and a series of mechanistic … WebIn this article, we report a preference of homochiral-type ligation of BINAP that produces SS-type ligand assembly onto the Au 11 clusters protected by diphosphine S,S-DIOP.The Au 11 clusters synthesized and isolated are Au 11 (S,S-DIOP) 4 (rac-/R-/S-BINAP), and their optical/chiroptical responses are characterized.Absorption spectra of these Au 11 …
