In the first examples of oxidative addition of tin−sulfur bonds to a transition-metal complex, the ring compounds (R2SnS)3 (R = Me, Ph) react with [PtMe2(tbu2bpy)] (tbu2bpy = 4,4-di-tert-butyl-2,2-bipyridine) to give the new luminescent organoplatinum(IV) complexes [PtMe2(R2SnS)2(tbu2bpy)] (1 and 2; R = Me and Ph, respectively), which contain the new five-membered PtSnSSnS ring. The complex [PtMe2{(SnMe2)S(SnPh2)S}(tbu2bpy)] (3) is formed selectively by any of the redistribution reactions between 1 and (Ph2SnS)3, 2 and (Me2SnS)3, or 1 and 2. |
