Significance

Rousseaux and co-workers disclosed a nickel-catalyzed alkyne hydrocyanation making use of glycolonitrile as active cyanating agent, which is formed in situ by reductive coupling of 2-methyl-2-phenylmalononitrile (MPMN) and formaldehyde.

Comment

The proposed mechanism is supported by mechanistic studies such as deuterium labeling and anion trapping experiments, ruling out the generation of a nickel-hydride intermediate.
