The coupling of α,β-unsaturated carbonyl compounds with aldehydes (the Baylis-Hillman reaction) was accelerated in the presence of a catalytic amount of 1,4-diazabicyclo[2,2,2]octane (DABCO) and lithium perchlorate in ether. A preliminary kinetic study revealed that the relative rate of the reaction using LiClO4 in ether was 8.0×102 times faster than that of the reaction without LiClO4.
在乙醚中催化量的1,4-二氮杂双环[2,2,2]辛烷(DABCO)和高氯酸锂的存在下,促进了α,β-不饱和羰基化合物与醛的偶联(Baylis-Hillman反应) 。初步动力学研究表明,使用的LiClO反应的相对速率4在乙醚中为8.0×10 2比没有的LiClO反应更快倍4。
