Data from the study of the insertion of aceto-, propio-, and benzonitrile into complexes of TaCl/sub 5/ with diethyl- and triethylamine in CCl/sub 4/ solutions have been discussed. It has been established that the nature of the ligands, rather than the nitrile being inserted into the complex, has a significant influence on the composition of the final products. In contrast to the case of acetonitrile, the insertion of propionitrile and benzonitrile into a complex is observed already at room temperature. On the basis of spectroscopic data it has been postulated that the carbon tetrachloride employed as a solvent accelerates the insertion of nitriles and promotes their deprotonation in the presence of an aprotic amine.
