The article discusses a research study on carbon (C)-oxygen (O) bonds involved in nickle (Ni)-catalyzed crossed couplings. It analyzes developments in cross-coupling, Ni-catalyzed homocoupling and C-O bonds functionalizations as well as reactions of aryl and vinyl sulfonates and sulfates when ...
cross-couplingligand designnickelsulfonamidesThe development of Ni‐catalyzed CN cross‐couplings of sulfonamides with (hetero)aryl chlorides is reported. These transformations, which were previously achievable only with Pd catalysis, are enabled by use of air‐stable (L )NiCl( o ‐tol) pre‐...

Transition-metal-catalyzed cross-couplings have been extensively used in the pharmaceutical and agrochemical industries for the construction of diverse C–C bonds. Conventional cross-coupling reactions require reactive electrophilic coupling partners, such as organohalides or sulfonates, which are not environm...

Palladiumand nickel-catalyzed cross-coupling reactions have been recognized as an indispensable tool for current organic synthesis. Among these reactions, Suzuki–Miyaura coupling is, arguably, of the greatest practical importance of these methods because of the attractive features of organoboronic acids:...
Aryl nitriles have been found to participate in cross-coupling and amination reactions via nickel-catalyzed activation of the C-CN bond. With the development of these synthetically useful transformations, aryl nitriles can now be considered along with aryl halides and sulfonates as viable substrates ...
