Deprotonation of the titanium formate complex [Ar(t-Bu)N]3TiOC(O)H with LiN(i-Pr)2 resulted in the release of free CO and the formation of a titanium(IV) oxoanion complex, isolated as its lithium salt.

A frustratedLewispair 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].
