)Z-Ala(CN)OCH 3 }(PPh 3 ) 2 ][BF 4 ] in good yield by reaction with the cationic derivative trans -[Pt(CF 3 ) 2 (solv)][BF 4 ] (solv = CH 2 Cl 2 ). The reactivity of the CN group in the complex trans -[Pt(CF 3 )Z-Ala(CN)OCH 3 }(PPh 3 ) 2 ][BF 4 ] with ClCH 2 CH 2 O − to the oxazoline ligand 2 was examined. The presence of the oxazoline ring in the final products was evidenced by IR, 1 H and 13 C NMR data and
