Benzene C−H Activation at a Charge Neutral Zwitterionic Platinum(II) Complex

Abstract

Cationic, coordinatively unsaturated metal centers exhibit a wide range of both stoichiometric and catalytic transformations. Such species are frequently generated by methide abstraction with a strong Lewis acid, or alternatively by protonation with an acid whose conjugate base is noncoordinating or weakly coordinating.3 We are targeting charge neutral, zwitterionic complexes that display reaction chemistry reminiscent of these reactive metal centers. Of particular interest is the development of species that exhibit transformations at X-H bonds, where an X-H bond refers generally to a C-H or other robust σ bond. A conceptual diagram illustrating this strategy is shown in Scheme 1.
