WebThe name reaction is a type of shorthand that avoids the need to give a lengthier explanation of the features of a particular transformation of interest. Mentioning the name reaction allows a knowledgeable listener to bring to mind the possible substrates, reaction conditions, or mechanistic details. Everyone in the field is expected to know a ... WebAdvances in nickel-catalyzed cross-coupling reactions have expanded the chemical space of accessible structures and enabled new synthetic disconnections. The unique properties of Ni catalysts facilitate the activation of traditionally inert substrates, tolerate alkyl coupling partners that undergo decomposition via β-hydride (β-H) elimination with Pd, and enable …
WebAbstract. The mechanism of many organic oxidation and reduction reactions can be described in terms of the formation and reaction of free radicals with metal complexes. Redox (trace-metal) catalysis also involves the oxidation and reduction of radical intermediates with a metal species which oscillates between several oxidation states (4).
