The imido titanium complex supported by a diamido-pyridine framework Ti(=NBut)[(2-C5H4N)C(R)-(CH2NSiMe3)2](py) (R = H, Me) reacts with 2,6-xylyl isocyanide to give the double insertion of the isocyanide into the imido titanium bond and formation of the corresponding four-membered titanacycle with one cr-Ti-C bond the... 

Addition of TiCl4 to a solution of trimethylsiloxyphenylisocyanide in //-hexane yields the air sensitive octahedral diisocyanide complex TiCl4(CNR)2 (Scheme 114). This complex crystallizes with one molecule of //-hexane. Its molecular structure has been determined by X-ray crystallography.227 The formations of isocyanide titanium complexes are studied as species related with the Passerini reaction assisted by TiCl4. Three classes of compounds were identified and exemplified by isolated complexes (Scheme 115).228... 

No homoleptic isocyanide complexes of niobium, tantalum, titanium, zirconium, and halfnium have yet been synthesized. The vanadium cation...

A number of titanium derivatives containing carbazole ligands have been isolated. Reaction of Ti(GH2Ph)4 with carbazole yields the dibenzyl complex Ti(GH2Ph)2(cb)2 (Scheme 45). The reaction of this compound with 2,6-dimethylphenyl isocyanide leads to titanium derivatives containing new carbon-carbon bonds (Section 4.05.2.3).109,110... 

The combination of titanium tetraisopropoxide and the TADDOL ligand (Lj in Scheme 11.7) in stoichiometric amount gave products 19 in moderate results (12-46% yields, 32-42% ee) [23]. Significantly better results (75-98% yield, 62-98% ee) were achieved by using tridentate indan(pybox) Cu(II) Lewis acid complex (L2 in Scheme 11.7) as catalyst. The use of carbonyl substrates capable of bidentate coordination was compulsory to give the a-addition to the isocyanide counterpart [24],...
