N-Trimethylsilylaminotitanium trichlorides, Me3Si(R)N-TiCl3 [R = ‘Bu (2a), SiMe3 (2b), 9-borabicyclo[3.3.1 ]nonyl (9-BBN) (2c)] react with the corresponding plumbylenes la c or with the lithium amides LiN(R)SiMe3 to give the bis(amino)titanium dichlorides 3a c, and 4 6. The titanium dichlorides 4-6 are the first examples, in which the titanium atom bears two different amino groups. The compound...

Reaction of the known titanocene Y 2 with methyl lithium at -15 degrees C yields bis-[(p-methoxybenzyl)cyclopentadienyl]titanium(IV) dimethyl (dimethyl titanocene Y, 3), a hitherto unknown, surprisingly robust titanium (IV) dimethyl species. Dimethyl titanocene Y was utilized in the preparation of several bis-[(p-methoxybenzyl)cyclopentadienyl]titanium(IV) dicarboxylates by the reaction with th...

Although fluoride induces corrosion in titanium in an oral environment, the influence of protein on this corrosion remains to be clarified. The objective of this study was to investigate suppression of fluoride-induced corrosion of titanium where albumin was either present in a solution or where albumin was preadsorbed on titanium. Titanium dissolution in titanium specimens and surface characte...

The treatment of titanium alkoxides with 1,5-pentanedioxime or 2,5-hexanedioxime resulted in the formation of complexes [{TiL(OR)2}2] in which the dioximate ligands (L) bridge a dimeric Ti2(μ2-OR)2 unit. The structures of the complexes were determined by single-crystal structure analysis, ESI mass spectrometry, and 1D and 2D solution NMR spectroscopy. In contrast, the treatment of titanium alko...
