Abstract
Attempts have been made to synthesise bimetallic alkoxides with the general formulae M[A1(OPri)4)]2 and PriOM [A1(OPri)4], M = Be(II), Zn(II), Cd(II) and Hg(II), by the reactions of the respective metal chlorides with KOPri and A1(OPri)3 in stoichio-metric ratios. The products PriOBe Al(OPri)4] and M[A1(Pri)4]2 (M = Be, Zn and Cd) were found to be volatile viscous liquids, soluble in benzene, carbon tetrachloride or chloroform. Hg[Al(OPri)4]2 (soluble in isopropanol only) could be isolated as a white solid which decomposed even at room temperature (∼20°C). Attempts to synthesise compounds with the general formula PriOM[A1(OPr1)4]2 (M = Zn, Cd and Hg) resulted in mixtures of benzene soluble (M = Zn and Cd) or isopropanol soluble (M = Hg) bimetallic isopropoxides with the formula M [A1 (OPri)4]2 and insoluble isopropoxides, M(OPri)2, along with KCl in stoichiometric ratios. All these products were susceptible to hydrolysis. The products exhibited monomeric character in benzene/chloroform solution. The new compounds have been characterized by elemental analysis, ir and pmr spectra.
