Amido- and aminophosphites and hydrospirophosphoranes can be used as ligands in the Pd-catalyzed allylation of ethyl malonate with ethyl (3-phenylprop-2-enyl) carbonate. Bidentate ligands (RO)(2)P-O(CH2)(n)-NR ' (2) (n = 2 and 3) were found to be the most effective ligands.

New acyclic aminophosphites (RO)2POCH2CH2NMe2 (PN) (R=Et, Pri, or adamantyl) characterized by various steric requirements of the phosphorus center were synthesized. The reactions of the aminophosphites with Pd(COD)Cl2 (COD is 1,5-cyclooctadiene) and [Rh(CO)2Cl]2 afforded the stable chelate mononuclear complexes PdCl2(PN) and RhClCO(PN), respectively. The structures of the resulting compounds were established
