    • A method is described in which hydroxyacetals or hydroxyacetal mixtures are used for catalytic C-O-C linking reactions to form ethers, especially by telomerizing diene systems, wherein palladium-(0) complexes are used as catalysts, carbonylating olefins with rhodium-(0) complexes and reacting the same with the hydroxyacetals or hydroxyacetal mixtures, and dimerizing the hydroxyacetals or hydroxyacetal mixtures with ruthenium-(0) complexes while eliminating water. The method allows the carbon chain of the hydroxyacetal or hydroxyacetal mixture used to be extended by several C atoms, the calorific value of the products to be increased, and the evaporation temperature to be lowered. The products can be used as fuels, solvents, detergents, cosmetics, softeners, stabilizers, pharmaceuticals, fungicides and microbicides, flavors, intermediate products, and as additives in various fields of application.
    • 描述了从hydroxyacetals或Hydroxyacetalgemischen催化COC-键形成于醚形成反应,尤其是由二烯系统,其中,钯(0)配合物用作催化剂,烯烃与铑(0)配合物和羰基化的调聚反应开始的处理他们的 与hydroxyacetals或共混物反应是还有hydroxyacetals的二聚化或 - 与钌的混合物(0)同时消除水络合物。 该方法允许使用的羟基缩醛或的碳链的延伸 - 几个C原子的混合物,并增加了产品的热值的和在蒸发温度的降低。 该产品可以用作燃料,溶剂,洗涤剂,化妆品,增塑剂,稳定剂,药物,杀真菌剂和杀微生物剂,香料物质,中间体和作为添加剂用于各种应用。
