A novel coupling reaction of α-halo ketones promoted by SmI3/CuI

Liu, Yongjun,Zhao, Hengmin,Tian, Guang,Du, Feng,Qi, Yan,Wen, Yonghong

, p. 26317 - 26322 (2016)

With SmI3 as the Lewis acid and catalyzed by CuI in DMF, α-haloketones were transformed unexpectedly into α-hydroxy-1,4-diketones in good to moderate yields. The mechanism was probed and a plausible reaction pathway was proposed. DMF was assumed to play a dual role both as a hydroxyl source and as a solvent.
