elemental analysis. FT-IR and NMR. Their reactivity has been investigated, the mixed-metal species Pr4TiO(OPri)14 and Y4PrO(OPri)13 were obtained. Ligand exchange reactions afforded [Pr4O2(OR)3(OR′)5]m species (R Pri, R′ C2H4NMe2, R SiMe3, R′ Pri) and [Pr(OC2H4NMe2) (thd)2]2. X-ray structure analysis of the adduct obtained by reaction of [Pr4O2(OC2H4OMe)8]m with trimethylphosphine oxide reveals
摘要研究了制备to醇盐的各种途径。获得了化合物,例如Pr 5 O(OR)13 [R = Pr i(1),Am 1],[Pr 4 O 2(ONp)8] m(Np =新戊基),[Pr(OC2H4NMe2)3] 3。通过of变质与相应的醇反应 双三甲基甲
硅烷基酰胺的醇解反应得到[Pr4O(ONp)10] m,[Pr4O2(ONp)8] m,Pr3(OR)9(ROH)2 [R = But,Amt]和[Pr4O2(OC2H4OMe)8] m(2a),后者的衍
生物说明了氧代物质形成的趋势。通过元素分析对化合物进行表征。FT-IR和NMR。研究了它们的反应性,获得了混合
金属物种Pr4TiO(OPri)14和Y4PrO(OPri)13。
配体交换反应提供[Pr4O2(OR)3(OR')5] m物种(RRPri,R'′C2H4NMe2,RSiMe3,R'Pri)和[Pr(OC2H4NMe2)(thd)2]
