Key Points

This research investigates the cooperative reactivity of halomethanes and silanes at a diplatinum complex.
Synthesis of the diplatinum(0) complex
Reaction with halomethanes (CH2X2, X = Cl, Br, I) and CCl4
Analysis of cooperative addition mechanisms
Facile addition of one C–X bond at each platinum site
Comparison between transannular addition and bridging tetrylenes
Observation of synergistic effects in reactivity

Abstract

With CH 2 X 2 (X = Cl, Br, I) and CCl 4 the diplatinum(0) complex ( μ -dmpm) 2 Pt 2 (nbe) 2 (dmpm = bis(dimethylphosphino)methane, nbe = norbornene) undergoes facile cooperative addition of one C–X bond at each Pt...
