“…The oxidative additions of Me 3 GeCl, Me 3 GeBr, and Me 3 SnCl to [PtMe 2 (bpy)] described here were first reported by Kuyper. , These reactions have been extended to the oxidative addition of a wide variety of germanium and tin reagents to platinum(II) complexes of the general formula [PtMe 2 (diimine)] (Schemes −4). The oxidative additions of Ge−X and Sn−X (X = Cl, Br, I) to platinum(II) proceeded rapidly and cleanly to give the platinum(IV) products in good yield.…”

“…There has been little study of the oxidative addition of group 14−halide bonds to platinum(II) except when the group 14 element is carbon. In one notable study, Kuyper , describe the oxidative addition of compounds ER n Cl 4- n (E = Sn, Ge; R = Me, Ph) to [PtMe 2 (bpy)]. The oxidative addition of silicon−chloride bonds was attempted but never observed.…”

The reactions of group 14 compounds Me n EX4-n (E = Si, Ge, Sn; X = Cl, Br, I) with electron-rich [PtMe2(diimine)] complexes give facile trans oxidative addition of the E−X bond (E = Si, X = Br, I; E = Ge, Sn, X = Cl, Br, I). The oxidative additions occur more readily for Me n EX4-n in the sequences X = I > Br > Cl and E = Sn > Ge > Si. The first stable silylplatinum(IV) complexes have been prepared in this way, and the X-ray crystal structure of [PtIMe2(Me3Si)(bpy)] shows an exceptionally long Pt−I bond length (2.963(1) Å) consistent with the high trans influence of the trimethylsilyl group. 1H NMR studies show that the oxidative addition involving germanium and tin reagents is easily reversible. Several of the platinum(IV)−tin complexes have a second molecule of tin reagent incorporated into the crystal lattice. The X-ray crystal structure of [PtIMe2(Me3Sn)(bpy- t bu2)]2·Me3SnI· CH2Cl2 shows two distinct complexes (1:1 ratio) to be present in the unit cell. The first is the product of trans oxidative addition, [PtIMe2(Me3Sn)(bpy- t bu2)], and the second is [PtIMe2(Me3Sn)(bpy− t bu2)]·Me3SnI. In this second complex the platinum-bound iodo ligand coordinates to the tin center of the Me3SnI molecule to give a trigonal-bipyramidal tin center.

“…Kuyper , has reported the reaction of various group 14−halide bonds in compounds of the type R n MX 4- n (M = C, Si, Ge, Sn, Pb; X = Cl, Br; R = Me, Ph; n = 0−3), to the electron-rich [PtMe 2 (NN)] complexes. These studies showed that several group 14−halide bonds readily undergo the oxidation reaction to afford stable platinum(IV) products of the type [PtXMe 2 (R n MX 3- n )(NN)], but Si−Cl addition is not observed.…”

“…It has been shown that the occupied d z 2 orbital of a d transition metal ion with square-planar coordination geometry can act as a potential donor to another metal ion (M) resulting in a dative M(d 8 )→M bond. Many examples of Pt(II)→M dative bonds have been reported. − However, this type of bond is generally supported by a bridging ligand 1 or a weakly bridging interaction …”
