The reaction of K 2 [PdCl 4 ] with (S,S)-(i-Pr) 2 eddip diester (diisopropyl (S,S)-2,2'-(1,2-ethanediyldiimino)dipropanoate) resulted in {PdCl 2 [(S,S)-(i--Pr) 2 eddip-κ 2 N,N']} (1) and {PdCl[(S,S)-(i-Pr)eddip-κ 2 N,N',κO]}(2) with one hydrolyzed ester group. The compounds were characterized by spectroscopic methods and it was proved that the reaction is diastereoselective ( 1 H-and 13 C-NMR) in the case of 2 (one diastereoisomer of four possible). The structure of 2 was determined by X-ray diffraction analysis, indicating that the product is the (R,R)-N,N' configured isomer. In contrast, the reaction yielding 1 produced two of three possible diastereoisomers. DFT calculations support the formation of two diastereoisomers of 1 and of one diastereoisomer of 2.
