✦ Synopsis

In a preceding paper [l] we reported the results of incorporating a diasterotopic isopropyl group at the terminal AA positions of complexes of the type cis-M(AA)zXz.

It was argued, on permutational grounds, that the steric course of the configurational changes in these &-type complexes can be rationalized in terms of the As averaging set [2]. Placement of the prochiral isopropyl group in the y-or (3-) position of the acetylacetonate (acac) ring in a M(AA)2X2 complex can, in principle, provide an opportunity to study the environmental averaging of terminal A groups, and the inversion of the molecular configuration independently.

The present work reports on our investigations of the configurational changes taking place in the complex Ti(3-l&H,-acac)&lz using the variable temperature nuclear magnetic resonance method.
