Two novel chiral rhodium complexes were successfully synthesized from the reaction of a new class of bidentate nitrogen ligands with RhCl3. 3H(2)O in ethanol under reflux. The crystal structure of 4a was unambiguously established by X-ray analysis. Their corresponding cationic metal complexes prepared in situ from the reaction of 4a or 4b with AgBF4 catalyze the enantioselective allylation of arylaldehydes with allylstannane in 5-50% ee, (C) 1999 Elsevier Science Ltd.
