Mix and match : A self‐assembled ligand library ( SAL XY ) affords a wide range of R / S ratios in Rh‐catalyzed asymmetric hydroboration (see scheme; nbd=2,5‐norbornadiene, R* is a chiral substituent). Ligand‐scaffold optimization reveals “substrate‐tailored” ligands that afford high regio‐ and enantioselectivity for a variety of ortho ‐substituted styrene derivatives.
