With funding from the National Natural Science Foundation of China (approval numbers: 91856104 and 21871145), Professor Ye Mengchun from Nankai University and Professor Yu Jinquan from the Scripps Institute in the United States have achieved important results in the bimetal-catalyzed selective olefination of pyridine C3–H.

Progress

The team designed a new bifunctional carbene ligand bridging Ni and Al bimetallic catalysts
.

The pyridine substrate is activated through Al coordination, and then the ligand is directed to the metal Ni to reach the pyridine C3 site, which realizes the remote C-H selective olefination reaction and solves the problem of the activity and selectivity of pyridine C3-olefination

This research has developed a new Ni-Al bimetallic catalytic system, which not only realizes a new mode of remote C-H activation, but also provides an efficient method for the late C3 olefination of pyridine derivatives with important biological activity
