Abstract

A ground-state [C.sub.2] trigonal-bipyramidal geometry adopted by 2,6-Bis(2,6-difluorophenyl)phenyldimethylsilanium ion in which fluorines from opposing 2,6-difluorophenyl groups coordinate to the apical positions of the pentavalent silyl cation is reported. The exchange of fluorine at silicon occurs via a disrotatory gearing mechanism wherein one fluorine remains coordinated to silicon throughout the circuit.

Abstract

Exploration of new organometallic systems based on polyhedral boron clusters has the potential to solve challenging chemical problems such as the stabilization of reactive intermediates and transition-state-like species postulated for E-H (E = H, B, C, Si) bond activation reactions. We report on facile and clean B-H activation of a hydroborane by a new iridium boron cluster complex. The product of this reaction is an unprecedented and fully characterized transition metal-stabilized boron cation or borenium. Moreover, this intermediate bears an unusual intramolecular B···H interaction between the hydrogen originating from the activated hydroborane and the cyclometallated metal-bonded boron atom of the boron cluster. This B···H interaction is proposed to be an arrested insertion of hydrogen into the B
