Iridium‐Catalyzed H/D Exchange at Vinyl Groups without Olefin Isomerization

Making the switch: The title reaction represents a rare example of olefinic CH activation without olefin isomerization. The conditions are sufficiently mild so that functional groups such as ketones, esters, nitriles, amines, sulfides, and alcohols are tolerated. This selectivity is demonstrated by deuterium labeling of several complex molecules.
