Organoplatinum Dendrimers Formed by Oxidative Addition

Abstract

A Pt14 dendrimer is the highest nuclearity complex obtained by the first convergent method for the synthesis of alkyl transition metal dendrimers. The product of the first growth cycle is 1, which forms by oxidative addition of 4,4′-bis(bromomethyl)-2,2′-bi-pyridine to [Me2Pt(tBu2bpy)] and subsequent introduction of a PtII center with [Pt2Me4-(μ-SMe2)].
