乙酰丙酮在微波和PTC条件下的双烷基化

Solid-Liquid Phase Transfer Catalytic SynthesisⅩⅢ. The Convenient Dialkylation of Acetylacetone in the Presence of Quaternary Ammonium Salts under Microwave Irradiation

在６５０Ｗ微波炉中进行乙酰丙酮的固液相转移催化烷基化反应。用一系列活泼卤代烃作为烷基化试剂，反应时间２分钟，即可顺利得到分离产率为６８～８４％的α，α－双烷基化产物。

The rapid dialkylation of acetylacetone with a series of halides was performed in 650W domestic miCrowave oven within 2 minutes under solid-liquid PTC condition,and the isolated yield of dialkylated products varying from 68 to 84%.
