  长链酰基辅酶和邻二酮

  摘要：

  研究了制备长链邻二酮的几种方法。酰基转移酶缩合，然后进行氧化，提供了一种制备对称化合物的极佳途径，但对于不对称二酮而言并不令人满意。后者由（i）由二烷基乙炔经半氢化，羟基化和用N-溴代琥珀酰亚胺水溶液氧化而制得；（ii）由α-乙酰氧基酰氯和双四氢吡喃基或二苄基烷基丙二酸酯的钠衍生物衍生，然后除去保护基并脱羧得到α-乙酰氧基-酮，然后将其水解和氧化。

  Metal salts of organic acids complexed with β-diketone compounds are multifunctional complexes useful in the formulation of stabilizers for halogenated resins. These complexes may be used jointly with other low toxicity intermediates, such as zinc or magnesium intermediates, to form effective stabilizers that are non-toxic and exhibit better performance than other known stabilizers, including those containing toxic heavy metals such as cadmium or lead. The complex is prepared utilizing a Claisen condensation reaction and precipitation with water and heptane.

  有机酸金属盐与β-二酮化合物形成的复合多功能配合物可用于制备卤代树脂的稳定剂。这些配合物可以与其他低毒性中间体（如锌或镁中间体）联合使用，形成有效的稳定剂，这些稳定剂是无毒的，并且比其他已知的稳定剂表现更好，包括含有有毒重金属如镉或铅的稳定剂。该复合物是通过Claisen缩合反应和水和庚烷的沉淀制备而成。
