Electrochemically promoted N-heterocyclic carbene polymer-catalyzed cycloaddition of aldehyde with isocyanide acetate
N-heterocyclic carbene (NHC) is a potent organic small-molecule catalyst. However, its high synthetic price and frequent use in combination with excess oxidants have limited its utilization in industrial produ...
