Internal alkynes were chemoselectively and diastereoselectively hydrogenated to the corresponding cis ‐alkenes in alcoholic suspensions of a copper‐loaded titanium(IV) oxide photocatalyst without the use of additives and a reducing gas, and alkynes having functional groups such as a nitrile group were doubly chemoselectively converted into the corresponding alkenes.
