molecules. This approach allowed a change between the favored formation of cyclic acetals and linear acetals, originating from the bridging of two diols with a carbon-dioxide based methylene unit. This new synthesis option paves the way to novel fuels, solvents, or polymer building blocks, by the recently established "bio-hybrid" approach of integrating renewable energy, carbon dioxide, and biomass in a direct
本文提出了一种过渡金属催化剂体系,该体系可通过二氧化碳,分子氢和生物质衍生的二醇的综合利用来选择性合成环状和线性缩醛。对底物范围的详细研究使反应的选择性得到了很大的指导,并证明了整合多种底物分子的可能性。该方法允许在有利的环状缩醛和线性缩醛的形成之间进行改变,这源于两种二醇与基于二氧化碳的亚甲基单元的桥接。通过最近建立的将可再生能源,二氧化碳和生物质直接催化转化的“生物混合”方法,这种新的合成方法为新型燃料,溶剂或聚合物构件铺平了道路。
