coupled with the second ‘double’ or pi bond. The sigma bond is no different from the bonds we’ve seen above for CH4, NH3or even H2O. We simply add a pi bond on top of the sigma to create the double bond (and a second pi bond to create a triple bond). ...

Following the groundbreaking efforts by Heck and co-workers in the late 1960s on palladium-catalyzed coupling reactions [24], remarkable advancements have been achieved in the functionalization of the less reactive sp2 C-H bonds. However, the more abundant sp3 C-H bonds remain underutilized due ...
