标题:在环境条件下通过(甲酸)-Pd/hpc-Nh2 系统选择性升级生物质衍生的苄基酮
摘要:升级生物质衍生的酚类化合物为生产高附加值的燃料和化学品提供了一种有价值的方法.然而,大多数成熟的催化系统即使在苛刻的反应条件下也表现出低加氢脱氧 (Hdo) 活性.在这里,我们发现以甲酸 (Fa) 为氢源的-nh 2修饰的分级多孔碳 (Pd/hpc-nh 2 ) 上负载的 Pd 对来自粗木质素衍生的含氧化合物的苄基酮的选择性 Hdo 表现出前所未有的性能.设计的实验和理论计算表明 H + /h-Fa 分解产生的物种加速了对苄基酮中羰基碳的亲核攻击,通过中间醇与 Fa 的酯化形成的甲酸盐物种加速了 C-O 键的断裂,在 30oc 下实现了香兰素152.5 H-1的 Tof升级,比传统 Hdo 工艺(~10 H-1,100oc-300oc)高 15 倍.这项工作提供了一条有趣的绿色途径,可以在温和的条件下仅从生物质中生产运输燃料或有价值的化学品.

权利人:ELEVANCE RENEWABLE SCIENCES
摘要:This disclosure relates generally to olefin metathesis, and more particularly relates to the synthesis of terminal alkenes from internal alkenes using a cross-metathesis reaction catalyzed by an olefin metathesis catalyst. According to one aspect, for example, a method is provided for synthesizing a terminal olefin, the method comprising contacting, in the presence of a ruthenium alkylidene metathesis catalyst, an olefinic substrate comprised of at least one internal olefin with a cross metathesis partner comprised of an alpha olefinic reactant, under reaction conditions effective to allow cross-metathesis to occur, wherein the reaction conditions include a reaction temperature of at least 35° C. The methods, compositions, reactions and reaction systems herein disclosed have utility in the fields of catalysis, organic synthesis, and industrial chemistry.
