Dihydrogen cleavage by a dimetalloxycarbene–borane frustrated Lewis pair†
Abstract
A frustrated Lewis pair of dititanoxycarbene [(Ti(N[tBu]Ar)3)2(μ-CO2)] (Ar = 3,5-Me2C6H3) and B(C6F5)3 cleaved dihydrogen under ambient conditions to give the zwitterionic formate [(Ti(N[tBu]Ar)3)2(μ-OCHO-ηO:ηO′)(B(C6F5)3)] and the hydrido borate [Ti(N[tBu]Ar)3][HB(C6F5)3].
