A 5,5'-Di-(protected)-2,2' -bifuran: wherein each R1 is independently an unsubstituted or substituted 5- or 6-member 1,3-dioxo-2-y1 ring radical. Processes for making the bifuran include coupling 2-(protected)-furfural. Processes for using the bifuran include deprotection, functionalization, and/or polymerization to form a polyester. The polyester can be a renewable, high-performing polyester offering a combination of low cost of production, high sustainability, and excellent performance.
一种5,5'-二-(保护基)-2,2'-联
吡喃:其中每个R1独立地是未取代或取代的5-或6-成员1,3-二氧杂-2-基环辅基。制备该联
吡喃的方法包括偶联2-(保护基)-
呋喃。使用该联
吡喃的方法包括去保护、官能化和/或聚合以形成聚酯。该聚酯可以是一种可再生、高性能的聚酯,提供了低生产成本、高可持续性和优异性能的组合。
