  [reaction: see text] A task-specific ionic liquid, [bmIm]OH, has been introduced as a catalyst and as a reaction medium in Michael addition. Very interestingly, although the addition to alpha,beta-unsaturated ketones proceeds in the usual way, giving the monoaddition products, this ionic liquid always drives the reaction of open-chain 1,3-dicarbonyl compounds with alpha,beta-unsaturated esters and

  [反应：见正文]在迈克尔加成反应中，已将一种特定任务的离子液体[bmIm] OH引入作为催化剂和反应介质。非常有趣的是，尽管以通常的方式添加α，β-不饱和酮，得到单加成产物，但这种离子液体始终驱动开链的1,3-二羰基化合物与α，β-不饱和酯和腈的反应。迈向双加成反应，仅需一步即可生产双加合物。

The Michael addition to α,β-unsaturated ketones proceeds in the usual way, giving the monoaddition products, whereas addition to α,β-unsaturated esters and nitriles leads exclusively to the bis-addition products. The α,β-acetylenic ketones

  碱性离子液体1-甲基-3-丁基咪唑鎓氢氧化物[bmIm] OH催化活性亚甲基化合物与共轭酮，羧酸酯和腈的迈克尔加成反应。它进一步催化将硫醇添加到α，β-炔基酮上，并使1,3-二羰基和-二氰基化合物烷基化。α，β-不饱和酮的迈克尔加成反应以通常的方式进行，得到单加成产物，而α，β-不饱和酯和腈的加成仅导致双加成产物。α，β-炔基酮与硫醇进行双重共轭加成，生成β-酮基1,3-二硫代衍生物。在烷基化反应中，无环的1，3-二酮被单烷基化，而环状酮在相同条件下进行二烷基化。所有这些反应均在没有任何有机溶剂的情况下进行。
