Abstract

A procedure for the direct synthesis of dialkoxyaluminum hydrides (RO)2AlH (R=Pri, But, and Et) from aluminum metal and corresponding alcohols in organic solvents (hydrocarbons, ethers) in the presence of catalytic amounts of tertiary amines (NMe3, NEt3) at a pressure of H2 of 80 to 350 atm and at a temperature of 100 to 160°C has been developed. A possible mechanism for the reaction was proposed. Thermal decomposition of (RO)2AlH was studied by differential thermogravimetric analysis (DTGA),27Al NMR spectroscopy, IR spectroscopy, and GLC.
