标题:高效的meerwein-Ponndorf-Verley降低了强大的锆-有机硼酸混合溶液
摘要:Meerwein-Ponndorf-Verley(mpv)反应是一种选择性还原羰基的有吸引力的方法,而先进催化剂的设计是这类有趣反应的关键.本文中,我们使用1,4-苯二硼酸(bdb)作为mpv还原的前体,制备了新型有机硼酸锆.制备的zr-Bdb对mpv还原各种生物质衍生的羰基化合物具有优异的催化性能(即,乙酰丙酸酯,醛和酮).更重要的是,由于硼酸根在氢源中对羟基的活化作用,配体上硼酸根的数目显着影响zr-有机配体杂化物的催化活性.详细的研究表明,Zr-Bdb的优异性能归功于zr 4+和硼酸盐的协同作用.值得注意的是,这是提高硼酸根基mpv反应中zr基催化剂活性的第一项工作.
