Titanium (IV) complexes based on substituted 2-[(2-hydroxyethyl)]aminophenols

Trapping an unprecedented Ti3C3 unit inside the icosahedral C80 fullerene: a crystallographic survey

“…The Ti-Ti distances among the three titanium atoms are 2.976Å for Ti1-Ti1A and 3.604Å for Ti1-Ti2 and Ti1A-Ti2, respectively, which are comparable to the values observed in organotitanium complexes, indicating weak metal-metal interactions between the titanium atoms. [27][28][29] From a geometric point of view, the three titanium atoms intercalate between the cage and the C 3unit, preventing the encapsulated carbon atoms from being merged with the cage framework.

“…S7 (ESI †) shows that the predominant localization of the LUMO is on the Ti 3 C 3 cluster (mainly on the Ti atoms), suggesting that the rst reduction step is ascribed to the alteration of the reduction behavior of the inner cluster, similar to the case of Sc 2 TiC 2 @I h -C 80 . 27…”

Titanium(IV) Complexes Based on Tri­dentate N,N,O Ligands – Synthesis, Structure, and Thermal Decomposition

“…Titanium complexes based on tridentate alkoxide O,N,O‐type ligands have a range of applications as catalysts in organic synthesis,1 initiators for alkene2,3 or lactone4,5 polymerization, and precursors for nanomaterials 6. The most characteristic ligand structures, including aminodialcohols,1a,3b,3c,7 aminophenols,8 2,6‐bis(alkylhydroxy)pyridines,9 aminodiphenols,10 and pyridinediphenols,3d,11 are presented in Scheme .…”

“…For titanium alkoxides (homoleptic alkoxides18b,25 or complexes of polydentate ligands),8,26 controlled hydrolysis is usually regarded as a route to Ti oxoalkoxides, although some authors still consider oxoalkoxides as products of uncontrolled (random) hydrolysis27 or simply do not discuss the appearance of the oxo groups. There are several cases of oxidative25d or thermal decomposition of simple Ti alkoxides [such as Ti(OEt) 4 in an autoclave],18b and there are no such examples so far for Ti alkoxides with polydentate ligands.…”
