metal ion coordination have been prepared and characterized. Bromine-substituted β-diketones were synthesized under Claisen−Schmidt-type condensation conditions. Vinyl groups were substituted for the halide by one of two types of Heck coupling with high-pressure ethylene. The type of Heck coupling employed was dictated by the thermal sensitivity of the substrate. Seven vinyl-substituted β-diketones were
已经制备并表征了用于金属离子配位的可聚合β-二酮。在克莱森-施密特型缩合条件下合成了溴取代的β-二酮。用高压乙烯与两种类型的Heck偶联中的一种,用乙烯基取代了卤化物。所采用的Heck耦合类型取决于基板的热敏性。用这种方法合成了七个乙烯基取代的β-二酮,包括几个新的。通过GC-MS,FT-NMR,FT-IR和微量分析对β-二酮进行了表征。
