A new and selective route for the synthesis of polymer precursors, primary diamines or N-substituted diamines, from dicarboxylic acids, diesters, diamides and diols using a Ru/triphos catalyst is reported. Excellent conversions and yields are obtained under optimised reaction conditions. The reactions worked very well using 1,4-dioxane as solvent, but the greener solvent, 2-methyl tetrahydrofuran, also gave very similar results. This method provides a potential route to converting waste biomass to value added materials. The reaction is proposed to go through both amide and aldehyde pathways.

在胺存在下由二羧酸及其衍生物加氢制取α，ω-二胺的新途径

报道了使用Ru / triphos催化剂从二羧酸，二酯，二酰胺和二醇合成聚合物前体，伯二胺或N-取代的二胺的新的选择性途径。在优化的反应条件下可获得出色的转化率和产率。使用1，4-二恶烷作为溶剂，反应效果很好，但是较绿色的溶剂2-甲基四氢呋喃也得到了非常相似的结果。该方法提供了将废物生物质转化为增值材料的潜在途径。建议该反应通过酰胺和醛途径。
