P,N-Bidentate aryl phosphite ligands based on chiral 2-imino-, 2-oxazolinyl and 2-oxazolidinyl phenols and their catalytic activity
Abstract
New P,N-hybrid aryl phosphites with distant imino, oxazolino and oxazolidino groups are effective chiral ligands in Pd-catalysed asymmetric allylic substitution reactions.
