Abstract
Treatment of [PtCl(Me)(dbbipy)] or [PtCl2(dbbipy)](dbbipy = 4,4′-di-tert-butyl-2,2′-bipyridine) with AgX (X = SO3CF3 or O2CCF3) gave the complexes [PtMe(SO3CF3)(dbbipy)]1, [Pt(SO3CF3)2(dbbipy)]2 and [Pt(O2CCF3)2(dbbipy)]5. The complexes [PtCl(SO3CF3)(dbbipy)]3 and [PtMe(O2CCF3)(dbbipy)]4 were prepared by the addition of HX to [PtCl2(dbbipy)] or [PtMe2(dbbipy)], respectively. Complex 1 reacted with CO to give the cationic carbonyl complex [PtMe(CO)(dbbipy)][SO3CF3]6a, which reacted with NEt2H to give an equilibrium with the corresponding carbamyl complex [Pt(CONEt2)Me(dbbipy)]7. In the first example of alkyl-ligand abstraction from a late-transition-metal complex by the powerful Lewis acid B(C6F5)3, the complexes [PtMeL(dbbipy)][BMe(C6F5)3](L = CO 6b or C2H48) were readily prepared from [PtMe2(dbbipy)] and B(C6F5)3 in the presence of L.Keywords
