绿色高效Ga（DS）_3在溶剂水中催化加成吲哚酮类化合物

摘要

采用三价镓十二烷基硫酸盐作催化剂,在溶剂水中,以Michael加成反应制备吲哚酮类化合物,并对其进行了FT-IR、1H NMR等表征。取吲哚1 mmol、不饱和酮1.2 mmol、催化剂Ga（DS）3（10%）、80℃,水溶剂中反应,在较佳反应条件下,得到一系列吲哚酮类化合物,产率均达到80.2%以上。%In water,using gallium（Ⅲ） dodecyl sulfate as a catalyst for the preparation of indolinone compounds by Michael addition reaction,and characterized by FT-IR and 1H NMR.Under better reaction conditions,a series of indolinone compounds could be obtained at 80 ℃ in water with indolinone 1 mmol,unsaturated ketone 1.2 mmol,Ga（DS）3（10%）,and the yield reached above 80.2%.
