Synthesis of zirconium() and hafnium() isopropoxide, -butoxide and -butoxide

We revisited the synthesis of zirconium( iv ) and hafnium( iv ) alkoxides, namely the metal isopropoxide isopropanol complex (M(OiPr) 4 ·iPrOH, M = Zr, Hf) and the metal sec - and tert -butoxide (M(O s Bu) 4 and M(O t Bu) 4 , M = Zr, Hf). We optimized the most convenient synthesis methods and compar...

Summary:We revisited the synthesis of zirconium( iv ) and hafnium( iv ) alkoxides, namely the metal isopropoxide isopropanol complex (M(OiPr) 4 ·iPrOH, M = Zr, Hf) and the metal sec - and tert -butoxide (M(O s Bu) 4 and M(O t Bu) 4 , M = Zr, Hf). We optimized the most convenient synthesis methods and compared the products with commercial sources. En route to the metal sec - and tert -butoxides, we synthesized the metal diethylamido complex (M(NEt 2 ) 4 , M = Zr, Hf). We revisited the synthesis of zirconium( iv ) and hafnium( iv ) alkoxides, namely the metal isopropoxide isopropanol complex (M(OiPr) 4 ·iPrOH, M = Zr, Hf) and the metal sec - and tert -butoxide (M(O s Bu) 4 and M(O t Bu) 4 , M = Zr, Hf).
