2-Methyl-2-(pyridin-2-yl)malononitrile: a site-selective cyano transfer reagent for photocatalytic cyanation reactions

Herein, we report the development of a carbon-bound radical cyanating reagent, 2-methyl-2-(pyridin-2-yl)malononitrile (MPYMN), which enables metal-free photocatalytic cyanation with high reactivity and site selectivity.
