Preparation and Properties of Ti-substituted N-Heterocycles The compounds (x = 2 to 6) have been prepared by transamination of Ti(NMe2)4 with the heterocyclic amines and have been characterised by elemental analyses and 1H NMR and IR spectroscopy. The dependence on both x and n of the thermal decomposition has been studied for the series and . The results can be interpreted in terms of the steric strain of the R2N and substituents. Apart from the piperidido groups none of the ligands exhibit protective group properties comparable to the R2N groups.
