B-H activation by frustrated Lewis pairs: borenium or boryl phosphonium cation?

Meghan A Dureen1, A Lough, Thomas M Gilbert, Douglas W Stephan.   

Abstract

Catechol borane reacts with the frustrated Lewis pairs tBu2RP (R = tBu, 2-C6H4(C6H5)) and B(C6F5)3 to give the species [(C6H4O2)BPtBu2R][HB(C6F5)3] that can formally be described as either borenium cation or boryl-phosphonium salts; the nature of these species was probed with DFT calculations.
