Copper-catalyzed cross-coupling reaction of α-sulfur-substituted alkylstannanes with acid chlorides

Copper compounds were found to catalyze the cross-coupling reaction of α-sulfur-substituted alkylstannanes with acid chlorides. Under the optimized conditions (CuF2 (1 mol %), 1,4-dioxane, 102 °C), various substrates coupled to afford the corresponding α-sulfur-substituted ketones in good yields.
