Abstract

A redox transmetallation/ligand exchange reaction between Al metal, Hg(C6F5)2 and 3,5-di-tert-butylpyrazole (tBu2pzH) in tetrahydrofuran (thf) yields [Al(tBu2pz)3(thf)] in which the six coordinate aluminium atom has two η2- and one η1-tBu2pz ligands. By contrast an analogous reaction in 1,2-dimethoxyethane (dme) gives the organoaluminium complex [Al2(tBu2pz)3(C6F5)2(OCH2CH2OCH3)] in which each aluminium atom has an η2-pyrazolate and a C6F5 ligand and the Al atoms are bridged by an η1:η1-tBu2pz ligand and a 2-methoxyethoxide ligand. In addition, [Al(tBu2pz)3] was isolated from the reaction mixture in a different form from that previously reprinted.
