Synthesis and Characterization of (MesGaO)9 (Mes = Me3C6H2) and Crystal Structure of the First Galloxane Comparable to Catalytically Active Aluminum Compounds†
The thermolysis of (Mes2GaOH)2·THF in toluene or 1,4-dioxane at 100 °C resulted in the formation of (MesGaO)9 (1). A byproduct of this reaction is Mes3Ga. Compound 1 was characterized by electron impact mass spectroscopy and single-crystal X-ray structural analysis. The structure consists of two six-membered (MesGaO)3 rings connected by three μ2-(MesGaO) units.
