2-Bromobenzaldehyde reacts with phenols in acetonitrile under carbon monoxide pressure in the presence of a catalytic amount of bis(triphenylphosphine)palladium(II) chloride to afford the corresponding 3-phenoxy-1,3-dihydro-1-isobenzofuranones in high yields.
2-溴苯甲醛在催化量的双(三苯基膦)钯(II)氯化物的存在下,在一氧化碳压力下与苯酚在乙腈中反应,以高收率得到相应的3-苯氧基-1,3-二氢-1-异苯并呋喃酮。
