The oxidative addition of PhSeX (X = Cl, Br, I) to Pt0 complexes of formula [Pt(N,N-chelate)(olefin)] is described. The reaction quantitatively affords the trigonal-bipyramidal products [PtX(SePh)(N,N-chelate)(olefin)] with the X and SePh fragments in the axial positions. NMR spectroscopic data have allowed us to gain insights into the geometrical isomerism of some of these complexes. The reactivity of the axial ligands towards electrophilic reagents is also investigated, and the molecular structures of [PtX(SePh)(dmphen)(dimethyl fumarate)] (X = Br, I) are compared.
