This article describes a stereochemical study on five-coordinate complexes of PtII containing a prochiral alkene (E-R1O2CCH=CHCO2R1) and a prochiral sulfide R2SR3, of general formula [PtMe(R2SR3)(dmphen) (E-R1O2CCH=CHCO2R1)]BF4. Through mono- and two-dimensional NMR spectroscopy, it was demonstrated that there is mutual recognition between the prochiral ligands in the presence of aryl sulfides R2SAr, whose origin was also explained. The equilibrium constants of sulfide exchange were also evaluated, which are in full agreement with the σ-donor properties of the ligands.

Abstract
This article describes a stereochemical study on five-coordinate complexes of PtII containing a prochiral alkene (E-R1O2CCH=CHCO2R1) and a prochiral sulfide R2SR3, of general formula [PtMe(R2SR3)(dmphen) (E-R1O2CCH=CHCO2R1)]BF4. Through mono- and two-dimensional NMR spectroscopy, it was demonstrated that there is mutual recognition between the prochiral ligands in the presence of aryl sulfides R2SAr, whose origin was also explained. The equilibrium constants of sulfide exchange were also evaluated, which are in full agreement with the σ-donor properties of the ligands.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
