Abstract: β, β-1, 3-Propylenedithio-α, β-unsaturated arylketones 2 via chemoselective 1, 2-addition with allyl or benzyl Grignard reagents afforded the corresponding carbinols 3 and 4.Catalyzed by silica gel, the carbinols 3 and 4 were converted to the β, γ-unsaturated arylke-tones 5, 6.The mechanism and reaction condition were discussed.

Key words: β,β-1,3-Propylenedithio-a, β-unsaturated arylketone, Grignard reagent, Decom-position, β,γ-Unsaturated arylketones
