The recent advances in visible-light photocatalytic deuteration of X–H, C–halogen, CC, and other bonds for the synthesis of deuterium-labeled organic molecules have been summarized according to the type of bond deuterated in the reactions.
A visible-light photocatalytic hydrogen evolution cross-coupling of silanes with H2O, alcohols, phenols, and silanols via synergistic combination of photoredox and polarity reversal catalysis has been developed.
