WebNew mechanistic studies have uncovered the role of salts and additives in the formation of active species in nickel-catalysed reactions. These results address ‘a fundamental gap in knowledge’, according to Eva Hevia, an expert in organometallic chemistry at the University of Bern, Switzerland, who wasn’t involved in the study. WebThese organometallic compounds are present in the reactions as intermediates. However, the mechanism is predicted around the copper cycle and palladium cycle. The formation of pi-alkyne complex and complex E is based on the presence of base. It makes the proton more acidic on alkyne.
