funcitonalized quinolines with the merits of broad substrate scope, good functional group tolerance, excellent hydrogen transfer selectivity, reusable earth-abundant metal catalyst, and operational simplicity. The developed chemistry paves the ways for further design of hydrogen transfer-mediated coupling reactions by developing heterogeneous catalysts with suitable supports.
由于喹啉的广泛应用,对这类产品的选择性结构的寻找一直是科学界的一个有吸引力的主题。在此,通过开发新的N掺杂ZrO 2@C负载的钴纳米材料,已成功地用作有效的催化剂,用于通过炔烃和炔酮还原环氧化2-硝基芳基羰基。催化转化可以合成具有宽底物范围,良好的官能团耐受性,优异的氢转移选择性,可重复使用的富地球金属催化剂以及操作简便等优点的功能齐全的喹啉。通过开发具有合适载体的非均相催化剂,已开发的化学方法为进一步设计氢转移介导的偶联反应铺平了道路。
