Group 13 alkyl compounds incorporating aliphatic and aromatic diolate ligands

摘要

This contribution deals with the synthesis, properties, and possible applications of complexes of aliphatic and aromatic diols with trialky-laluminum, -gallium, and -indium. The influence of steric hindrances of diolate units, the bulkiness of alkyl groups bonded to metal atoms, and the electron-withdrawing effects of ligands on the reaction courses and the structure of the products are shown and discussed. Reactions of binuclear metallane diolates, {~tBu_4M_2[diol-(H)]_2} (M = Al, Ga), with group 13 metallanes and transition metal chlorides are presented as a route to mixed-ligand and mixed-metal complexes. Replacement of ~tBu_2M with Me_2M units (transmetallation reaction) is presented as another method of mixed-complex synthesis.
