我们已经确定了一种阳离子铑（I）-dppf络合物催化烯丙基炔丙基醚异构化为丙二烯醛，在室温至40 ℃范围内产率良好。另一方面，联烯醛的羰基迁移反应进一步进行，在80 ℃下以良好的产率得到二烯醛。
We have established that a cationic rhodium(I)-dppf complex catalyzes isomerizations of allyl propargyl ethers to allenic aldehydes in good yields from room temperature to 40 degrees C. On the other hand, carbonyl migration reactions from allenic aldehydes further proceed to give dienals in good yields at 80 degrees C.
