Alkene Oxidation by a Platinum Oxo Complex and Isolation of a Platinaoxetane
摘要:
Oxo complex [(1,5-COD)4Pt4(mu3-O)2Cl2](BF4)2 (1) reacts readily with ethylene and norbornylene. The ethylene reaction yields acetaldehyde and a 1:1 mixture of (1,5-COD)Pt(Cl)(CH2CH3) (2) and [(1,5-COD)Pt4(eta3-CH2CHCH(CH3))](BF4) (3), while the norbornylene reaction yields a platinaoxetane complex, the first metallaoxetane to be obtained from the reaction of an oxo complex and an alkene.

The Pt(II) complexes (1,5-COD)Pt(OTf)2 and [(COD)Pt(THF)(OTf)]OTf react readily with alkenes (ethylene, cyclopentene, norbornenes) to give coupling products via HOTf elimination. With propylene a simple allyl complex is obtained.
