A modular approach to a new class of structurally diverse bidentate P/N, P/P, P/S, and P/Se chelate ligands has been developed. Starting from hydroquinone, various ligands were synthesized in a divergent manner via orthogonally bis-protected bromohydroquinones as the central building block. The firs

## Abstract Seven members of a new class of chiral P‐monodentate cationic phosphites and diamidophosphites have been synthesized for the first time and tested as ligands in asymmetric transition metal catalysis. Up to 96 % __ee__ was achieved in the rhodium‐catalyzed asymmetric hydrogenation of fun
