Recent Advances in the Nickel‐catalysed Electrochemical Coupling Reactions with a Focus on the Type of Bond Formed

Abstract Despite being around for many decades, electrochemical metal catalysis has recently widened the realm of electrochemical synthesis by merging sustainable electrosynthesis and tremendous metal catalysis. As the electric current can be controlled to stimulate the development of reactive intermediates and catalysts without the use of external oxidising or reducing agents and considering that it is more selective, generates less waste, and works under reasonable conditions, this strategy represents an eco‐friendly and economically sustainable method. Nickel can be used efficiently in electrochemical metal‐catalysed reactions owing to its inexpensive nature, high reactivity towards less reactive electrophiles and unique single electron transfer (SET) catalytic cycle. This review covers the recent advances in nickel‐catalysed electrochemical coupling reactions from 2017 to 2022, with a focus on different reactions that forge C−C or C‐heteroatom bonds.
