Room-Temperature β-H Elimination in (P2P)Pt(OR) Cations: Convenient Synthesis of a Platinum Hydride
摘要:
In situ-generated [(BINAP)(PMe3)Pt][BF4](2) reacts with benzyl alcohol at RT to yield [(BINAP)(PMe3)Pt-H][BF4] and benzaldehyde. This reactivity contrasts similarly ligated platinum-alkyl species, which are stable to beta-hydride elimination even at elevated temperatures. Protonolysis of the platinum hydride leads to a species that is readily substituted by weakly coordinating ligands (acetone, pentafluorobenzonitrile).
