Imido Derivatives of Titanium (IV)

Reactions of titanium(IV) isopropoxide with acetamide, benzamide, and nicotinamide in different stoichiometric ratios in anhydrous benzene yielded imido derivatives of type (PriO)4-nTi(NHOCR)n where n = 1, 2, 3, and 4; R = CH3, C6H5, and C5H4N. All these complexes are insoluble in common organic solvents suggesting their polymeric nature. All these derivatives, with the exception of three which have characteristic melting points, did not sublime at 250°C in vacuo nor did they appear to decompose appreciably below 300°C. I.R. spectra of these derivatives are discussed. Imido-Derivate des Titan(IV) Ti(PriO)4 reagiert in Benzol mit Acetamid, Benzamid bzw. Nicotinamid in verschiedenen stochiometrischen Verhaltnissen unter Bildung von (PriO)4-nTi(NHOCR)n (n = 1, 2, 3 und 4; R = CH3, C6H5, C5H4N); die Verbindungen sind in den ublichen Losungsmitteln unloslich und offenbar polymer; sie sind auch im Vakuum bei 250°C nicht fluchtig und zersetzen sich unterhalb 300°C nicht.
