The one-pot, two-step synthesis of wax esters was successfully conducted by consecutive homogeneous ruthenium-catalysed hydrogenation–dehydrogenation reactions of fatty acid methyl esters, in the absence of solvent and of base additive. Under optimized conditions, excellent conversion and selectivity were reached. Furthermore, physicochemical investigations revealed that the resulting compounds display properties similar to benchmark commercial products extracted from natural sources of lesser availability compared to the herein considered bioresources, making this chemical route very promising regarding further potential industrial implementation.

连续一锅两步催化从脂肪酸甲酯无溶剂和无碱合成蜡酯

在不存在溶剂和碱添加剂的情况下，通过连续的均相钌催化脂肪酸甲酯的加氢-脱氢反应，成功地完成了一锅两步蜡酯的合成。在优化的条件下，可获得出色的转化率和选择性。此外，理化研究表明，与本文考虑的生物资源相比，所得化合物显示出与从自然资源中提取的基准商业产品相似的性能，而天然来源的资源与本文中所考虑的生物资源相比，具有较低的可利用性，因此该化学方法在进一步的潜在工业应用方面非常有前途。
