工作介绍
1. 过渡金属催化的羧化反应及脱羧反应[1]
CO2是自然界广泛存在的一碳结构单元,可作为羧基的前体用于合成化学中,如传统的格氏试剂可与其反应得到羧酸产物。金属试剂与其反应都是当量级别的,Ruben教授则致力于催化反应的研究,实现惰性键的直接羧化反应。从早期的惰性金属试剂如锌试剂、锡试剂、硼试剂[2a]开始,逐步到C-X键[2b] (sp2, sp3),不饱和的C-H键[2c](烯烃,炔烃,联烯,二烯,二炔等),C-H键官能团化羧化反应[2d]等。
在2017年,Ruben教授实现了chain-walking类型的远程C-H键羧化反应[3],该工作发表于nature中。在该篇工作中,链上任意的烷基溴在反应中通过多次β-H消除和烯烃插入的过程,移动到端位或更加稳定的C-Ni键处,继而发生羧化反应(如图1-b所示)。而如图1-c所示,C-Br键所在的位置不影响反应的选择性。
远程C-H键羧化反应 (Nature 2017, 545, 84-88.)
2.过渡金属催化的C-O键断裂及相应转化[4]
金属催化的C-O键断裂用于偶联反应早已有广泛的应用,但此类C-O键都比较活泼,易于氧化加成,如OTf, OMs和酯基或酰胺基(I, II)等,并且反应会产生当量的副产物,原子经济性大大降低。Ruben教授致力于简单C-O键的断裂及其后续的转化,如由苯酚得到的甲基芳基醚类。
按照反应的成键类型,其主要转化可分为3类:(1)C-C成键,传统的偶联反应如,Kumada, Suzuki, Negishi, Heck以及α-芳基化都能实现;(2)C-N成键;(3)C-X成键,此类是Ruben教授的研究重点,具体包括还原反应[5a](C-H成键),硼化[5b](C-B成键),锡化反应[5c]以及C-Si成键[5d]。
