Article abstract of DOI:10.1246/cl.1981.993

Reactions of internal acetylenes with CO in alcohols gave 5-alkoxy-3,4-disubstituted-2(5H)-furanones in good yields in the presence of rhodium catalysts containing basic alkali metal salts, e.g., Rh4(CO)12 or RhCl2*3H2O in combination with sodium carbonat
