Abstract

Abstract The oxidative addition of PhSe–X molecules (X=Cl or Br) to Pt(II) complexes of formula [PtR(R ′)( N, N-chelate)] [R, R ′=Me, CH(CO 2Me) 2, CH(CO 2Me)(CN); N, N-chelate=4,4 ′-( tert-butyl) 2-2,2 ′-bipyridine] is described. The reaction quantitatively affords octahedral products [PtR(R ′)(SePh)(X)( N, N-chelate)], and is highly selective, since only the isomers with -X and -SePh in trans position are obtained. When R=R ′=CH(CO 2Me) 2 or R=R ′=CH(CO 2Me) 2(CN) an irreversible reductive elimination takes place in solution, giving rise to Pt(II) compounds [PtR(X)( N, N-chelate)] and organoselenium molecules PhSeR ′.
