【摘要】 本文研究了两种不同的苯基烷基砜与α,β-不饱和羰基化合物的共轭加成反应,发现其中苯基烷基砚与双缩丙酮在甲醇-二甲亚砜体系中的加成,不是生成1,2-或1,4-加成物,这可能是一个反常的反应,合成的产物中,有五种以前未见报道,产物的结构经IR,MS,HNMR等物理手段得到证实.更多还原

【Abstract】 The conjugate additions of a, β-unsaturated carbonyl compounds with two different alkylphenylsulfones were studied in this paper. The addition reaction of phenylbenzylsulfone with mesityl exide at methanol-DM SO system is not to produce 1, 2-or 1, 4-addition products, it is an abnormal reaction. The products were identified by mp, IR, 1H-NMRandMS. (Ⅱ) . (Ⅲ) . (Ⅳ) . (Ⅴ) . (Ⅵ) . are all new compounds.更多还原
