English abstract:
Aluminum alkoxides were modified with a series of TM-ketoesters and dialkylmalonates to give complexes of the general formulas [Al(OR)2(TM-diketonate)]2 and Al(TM-diketonate)3. The use of ligands bearing additional functional groups allows synthesis of precursors for inorganicorganic hybrid materials were synthesized. The influence of varying the ester-alkoxo groups on structure and reactivity was studied using NMR, IR and XRD techniques. Transesterification as a possible
side reaction affecting the structure of the products was studied and found to be crucial for the reaction with sterically less demanding malonates.
