The reactions of the dinuclear phosphorus ylide gold(I) complexes 2, 1, and 2, 2, with the alkyl halides MeI, (Me)3SiCH2I, and PhCH2Br have been studied.It is observed by 1H NMR spectroscopy that equilibrium is rapidly achiev

In addition to establishing the reversible nature of the oxidative addition of RX (R = CH3, CD3; X = Br, I) to [Au(CH2)2PPh2]2, we have observed that [Au(CH2)2PPh2]2 catalyzes halogen exchange between CH3Br and CD3I as well as between [Au(CH2)2PPh2]2Br2 and CH3I in CDCl3. The results of attempted halogen exchange with a variety of alkyl halides suggests that a SN2 process is likely via the formation of [[Au(CH2)2PPh2]2CH3] +I-; thus the dinuclear gold(I) complex effects exchange by ionization of CH3I.
