remains in high demand. Described here is a nickel‐catalyzed three‐component reductive carbonylation method for the synthesis of dialkyl ketones. A wide range of both symmetric and asymmetric dialkyl ketones can be accessed from alkyl halides and a safe CO source, ethyl chloroformate. The approach offers complementary substrate scope to existing carbonylation methods while avoiding the use of either toxic

Oxidative addition of benzylic halides to nickel in the metallic state followed by insertion of carbon monoxide generated fromalkyl oxalyl chlorides proceeded smoothly to give symmetrical 1,3-diarylpropan-2-ones in moderate yields.
