Abstract
Here we review the synthesis literature towards zirconium(IV) and hafnium(IV) isopropoxide isopropanol complex (M(OiPr)4.iPrOH, M = Zr, Hf) and zirconium(IV) and hafnium(IV) tert-butoxide (M(OtBu)4, M = Zr, Hf). We optimized the most convenient syntheses methods and compare the products with commercial sources. En route to the metal tert-butoxides, we synthesized the metal diethylamido complex (M(NEt2)4, M = Zr, Hf).
