| Abstract: | Reaction of trans-Pt(H)2(PCy3)2], 1, with 60]fullerene at room temperature affords Pt(PCy3)2(η2-C60)], 2, in nearly quantitative yield. The most probable reaction pattern is the insertion of a fullerene 6,6 junction onto a Pt-H bond yielding an η1 alkyl derivative which, after hydrogen extrusion, gives 2. On the other hand, addition of 1 to different electron-deficient olefins, such as dimethyl maleate and fumarate, furnishes mixtures of both η1 metal—alkyl and η2 metal—olefin derivatives. If tetrachloroethylene is used as 2π component, trans-PtCl(H)(PCy3)2] forms exclusively. |
