“Roll-over” Cyclometalation of 2,2′-Bipyridine Platinum(II) Complexes in the Gas Phase: A Combined Experimental and Computational Study

Abstract	In a combined experimental/computational investigation, the gas-phase behavior of cationic $[Pt(bipy)(CH_{3})((CH_{3})_{2}S)]^{+}$ (1) (bipy=2,2′-bipyridine) has been explored. Losses of $CH_{4}$ and $(CH_{3})_{2}S$ from 1 result in the formation of a cyclometalated 2,2′-bipyrid-3-yl species $[Pt(bipy−H)]^{+}$ (2). As to the mechanisms of ligand evaporation, detailed labeling experiments complemented by DFT-based computations reveal that the reaction follows the mechanistically intriguing “roll-over” cyclometalation path in the course of which a hydrogen atom from the C(3)-position is combined with the Pt-bound methyl group to produce $CH_{4}.$ Activation of a CH-bond of the $(CH_{3})_{2}S$ ligand occurs as well, but is less favored (35 % versus 65 %) as compared to the C(3)H bond activation of bipy. In addition, the thermal ion/molecule reactions of $[Pt(bipy−H)]^{+}$ with $(CH_{3})_{2}S$ have been examined, and for the major pathway, that is, the dehydrogenative coupling of the two methyl groups to form $C_{2}H_{4},$ a mechanism is suggested that is compatible with the experimental and computational findings. A hallmark of the gas-phase chemistry of $[Pt(bipy−H)]^{+}$ with the incoming $(CH_{3})_{2}S$ ligand is the exchange of one (and only one) hydrogen atom of the bipy fragment with the CH bonds of dimethylsulfide in a reversible “roll-over” cyclometalation reaction. The $Pt^{II}-mediated$ conversion of $(CH_{3})_{2}S$ to $C_{2}H_{4}$ may serve as a model to obtain mechanistic insight in the dehydrosulfurization of sulfur-containing hydrocarbons.
