Preparation and Reactivity of the Platinum(0) Anion [(Me2NCS2)Pt(PEt3)]-
摘要:
he first monometallic anionic complex of platinum(0), [(Me2NCS2)Pt(PEt3)]-, has been prepared from the reaction of butyllithium or lithium diisopropylamide and (Me2NCS2)Pt(PEt3)H. The anion decomposes in solutions warmed above 0-degrees-C, but its P-31 NMR spectrum can be observed at -41-degrees-C. By proper manipulation of the reaction conditions, the anion reacts successfully with triphenyltin chloride, methyl iodide, or iodine to yield (Me2NCS2)Pt(PEt3)SnPh3, (Me2-NCS2) Pt(PEt3)Me, and (Me2NCS2)Pt(PEt3)I, respectively.
