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 RhCl3·3H2O in combination with sodium carbonate or sodium acetate.
在含有碱性碱金属盐,例如 Rh4(CO)12 或 RhCl3·的铑催化剂存在下,内乙炔与 CO 在醇中的反应以良好的收率得到 5-烷氧基-3,4-二取代-2(5H)-呋喃酮3H2O 与碳酸钠或醋酸钠结合。

reactions of internal acetylenes with ethylene and CO in protic solvents, e.g., ethanol, gave 3,4-disubstituted-5-ethyl-2(5H)-furanones in good yields. By using propylene or methyl acrylate instead of ethylene, small amounts of 5-n-/iso-propyl-2(5H)-furanones or 5-[2-(methoxycarbonyl)ethyl]-2(5H)-furanone were obtained.
