and biologically compatible. A green procedure has been developed for the vinylation of carbohydrates by using readily available calcium carbide. Various carbohydrates were utilized as starting materials, resulting in mono‐, di‐, and tetravinyl ethers in high to excellent yields (81–92 %). The synthesized biobased vinyl ethers were utilized as monomers in free radical and cationic polymerizations. A
从可再生资源合成化学物质和材料是现代科学的主要目标之一。碳水化合物代表了极好的可再生天然原料,具有生态友好性,廉价和生物相容性。通过使用现成的电石,已经开发了一种绿色方法,用于碳水化合物的乙烯基化。各种碳水化合物被用作原料,以高到极好的收率(81–92%)产生单,二和四乙烯基醚。合成的生物基乙烯基醚被用作自由基和阳离子聚合反应的单体。在合成材料中实现了光滑表面和固有微隔室的独特组合。制备了两种类型的生物基材料,其中包括微球和聚合物中的固有中空隔室。
