摘要:使用甲醇(meoh)进行了卤化镧[lax(3)]衍生物的醇溶化作为降低labr(3)闪烁体生产温度的一种手段的首次研究.最初,通过在室温下简单地将1溶解在meoh中,研究了{[la(micro-Br)(h(2)o)(7)](br)(2)}(2)(1)的脱水.分离出混合的溶剂化物单体[la(h(2)o)(7)(meoh)(2)](br)(3)(2)化合物,其中la金属中心通过与两种其他的meoh溶剂,但必须将内球br转移到外球.为了尝试将1的甲醇中的反应混合物在cah(2)上干燥,分离了[ca(meoh)(6)](br)(2)(3)的晶体.在回流温度下将化合物1溶解在meoh中,导致分离出异常结构,该结构被确定为盐衍生物{[labr(2.75)* 5.25(meoh)](+ 0.25)[labr(3.25)* 4.75(meoh)](-0.25)}(4).最终,通过将干燥的labr(3)溶

摘要:The present invention relates to a process for hydrocyanating a hydrocarbon-based compound containing at least one ethylenic unsaturation by reaction in liquid medium with hydrogen cyanide in the presence of a catalyst comprising a metal element chosen from transition metals and an organophosphorus ligand, characterized in that the organophosphorus ligand is a monodentate organophosphorus compound. The present invention is in particular useful for the synthesis of adiponitrile from butadiene.
