Tertiary propargylic alcohols reacted with carbon monoxide in the presence of catalytic quantities of a cationic palladium(II) complex, [Pd(CH3CN)2(PPh3)2](BF4)2, to afford 2(5H)-furanones and/or 2,3-dienoic acids, the precursor of the furanones, in good yields under mild conditions.
在催化量的阳离子钯(II)络合物[Pd(CH 3 CN)2(PPh 3)2 ](BF 4)2存在下,叔炔丙醇与一氧化碳反应,得到2(5H)-呋喃酮呋喃酮的前体和/或2,3-二烯酸,在温和条件下收率高。
