In this paper we describe the preparation and characterisation, by single-crystal X-ray diffraction, of twelve ZrIV/HfIV complexes based on piperazine or homopiperazine salan ligands. With the piperazine ligands, a mixture of species was observed and

Herein we report the synthesis and characterisation of a series of Zr(iv) 2,2'-bipyrrolidine-salan derived complexes and their exploitation for the ring opening polymerisation of rac-lactide to afford highly isotactically enriched polymers.

In this paper nine various salalen ligands have been prepared and characterised. The steric and electronic effects of both the salen and salan fragments have been varied in a systematic fashion to ascertain how this affects the selectivity for the RO

In this paper a series of eight Ti(IV) piperazine based complexes have been prepared and fully characterised in the solid-state by X-ray crystallography and in solution via NMR spectroscopy. In the solid-state either Ti(2)(L)(O(i)Pr)(6) or Ti(2)(L)(2

In this paper we have prepared a series salen derived ligands based on a trans-1,4-diaminocyclohexane backbone. The ligands could be easily complexed to either Ti(IV) or Al(III) metal centres generating complexes with formulae Ti2(OiPr)6(L) and Al2(M

In this paper we report the synthesis and characterisation of a series of Al(iii)-homopiperazine complexes. The ortho substituent has been varied from H, Me, tBu to investigate the effect this has on the solid-state structures and on the catalytic ac

Background The area of biodegradable/sustainable polymers is one of increasing importance in the 21st Century due to their positive environmental characteristics. Lewis acidic metal centres are currently one of the most popular choices for the initia
