Abstract
PURPOSE: To obtain the titled compound in high yield useful as a raw material compound for synthetic resins, dye, drugs, agricultural chemicals, etc., by reacting a furan compound with an olefinic compound using a rhodium complex as a catalyst in the presence of carbon monoxide.
CONSTITUTION: A furan compound shown by the formula I (R1, R2, and R3 are H, alkyl, aryl, acyl, etc.) (e.g., 2-methylfuran) is reacted with an olefinic compound shown by the formula II (R4 is H, alkyl, etc.; R5 is alkoxycarbonyl, formyl, etc.) having an electronegative substituent group using a rhodium complex [e.g., Rh4(CO)12] consisting essentially of rhodium carbonyl as a catalyst in the presence of carbon monoxide at 150W300°C to give the desired compound shown by the formula III. The reaction in the presence of carbon monoxide suppresses the decomposition of the catalyst and preserves the activity for a long time.
