The reaction of Bis(cyclopentadienyl)titanium(III) chloride with organic azides

Abstract

Bis(cyclopentadienyl)titanium(III) chloride reacts with organic azides with the liberation of nitrogen and the formation of nitrogen-bridged Ti^1V compounds of varying thermal stability. Whhen the reaction is carried out in xylene, the initial products from phenyl and p-chlorophenyl azide can be isolated in an impure state, although they disproportionate on attempted purification. In tetrahydrofuran solution all the azides studied yield products which cannot be isolated, since they are transformed rapidly into mixtures of bis(cyclopentadienyl)titanium dichloride and other products.
