SYNTHESIS OF BIMETALLIC[SN(IV),AL(III)]-MU-OXOISOPROPOXYACETATE AND BIMETALLIC[SN(IV),AL(III)]-MU-OXOISOPROPOXIDE AND THEIR ACETYLACETONE AND BENZOYLACETONE DERIVATIVES

Bimetallic [Sn(IV),Al(III)]-mu-oxoisopropoxyacetate [Bu2Sn(OAc)OAl(OiP r)2] and bimetallic [Sn(IV),Al(III)-mu-oxoisopropoxide [Bu2SnO2Al2(OiP r)4] have been synthesized by thermal condensation of dibutyltin diace tate with aluminium isopropoxide in 1:1 and 1:2 molar ratio, respectiv ely. Reactions of these compounds with acetylacetone and benzoylaceton e in these molar ratios yielded compounds of the type [Bu2Sn(OAc)OAl(O iPr)L], [Bu2Sn(OAc)OAlL2], [Bu2SnO2Al2(OiPr)3L] and [Bu2SnO2Al2(OiPr)2 L2] (where L = acetylacetonate or benzoylacetonate anion). The mu-oxo compounds and their derivatives have been characterized by elemental a nalysis and spectroscopic techniques (IR, H-1 NMR, C-13 NMR, Al-27 NMR and Sn-119 NMR).
