A thermal cross-coupling reaction of α-sulfur-substituted alkylstannanes with acid chlorides is described. A range of substrates can be used for the present reaction and the reaction proceeds by just mixing two components under reflux in mesitylene to give the corresponding α-sulfur-substituted ketones in good yields.

Copper compounds were found to catalyze the cross-coupling reaction of a-sulfur-substituted alkylstannanes with acid chlorides. Under the optimized conditions (CuF2 (1 mol %), 1,4-dioxane, 102 degrees C), various substrates coupled to afford the corresponding a-sulfur-substituted ketones in good yields. (C) 2013 Elsevier Ltd.
