| Abstract | New chiral P,N-hybrid aryl phosphites have been obtained by one-step phosphorylation of amino and imino alcohols. Complexation of the new ligands with [Rh(CO)(2)Cl](2), [Pd(COD)Cl-2] and [Pd(allyl)Cl](2) was found to give chelate complexes [Rh(CO)Cl(eta(2)-(PN)-N-boolean AND)], [PdCl2(eta(2)-(PN)-N-boolean AND)] and [Pd(allyl) (eta(2)-(PN)-N-boolean AND)]Cl-+(-), respectively. With these new P,N-ligands, up to 82% ee enantioselectivity was achieved in the Pd-catalysed alkylation of ethyl 3-penten-2-yl carbonate with dimethyl malonate, up to 80% ee in the Pd-catalysed sulfonylation of methyl 3-penten-2-yl carbonate with sodium p-toluenesulfinate, and up to 50% ee in the Rh-catalysed hydrosilylation of acetophenone with diphenylsilane.
