Reactions of organomanganese compounds RMnCl (R = 3-sulfolen-2-yl or 5-methyl-3-sulfolen-2-yl) with allyl or propargyl bromides afford the corresponding 2-substituted or 2,5-disubstituted 3-sulfolenes in high yields. Thermolysis of the cross-coupling products results in 1,3,6-trienes or 1,3-dien-6-ynes.
