[reaction: see text] BINOL-based diphosphonites having achiral backbones are useful ligands in the Rh-catalyzed conjugate addition of arylboronic acids to alpha,beta-unsaturated carbonyl compounds. The nature of the achiral backbone determines the direction and degree of enantioselectivity, with er values of
