Dihydrogen cleavage by a dimetalloxycarbene-borane frustrated Lewis pair
Résumé
A frustrated Lewis pair of dititanoxycarbene [(Ti(N[Bu-t]Ar)(3))(2)(mu-CO2)] (Ar = 3,5-Me2C6H3) and B(C6F5)(3) cleaved dihydrogen under ambient conditions to give the zwitterionic formate [(Ti(N[Bu-t]Ar)(3))(2)(mu-OCHO-eta O:eta O ')(B(C6F5)(3))] and the hydrido borate [Ti(N[Bu-t]Ar)(3)][HB(C6F5)(3)].
