研究发现, 2,4,6-三苯基吡喃盐与三烷基(芳基)膦化合物PR3 (R＝Me, Et, Ph)可以发生两分子的共轭加成反应, 生成结构新颖的开环产物季鏻盐1. 通过1H NMR, 13C NMR, 31P NMR, 质谱和元素分析表征, 确定了反应产物的最终结构.

关键词: 三烷基(芳基)膦, 共轭加成, 吡喃盐, 季鏻盐

The unprecedented nucleophilic addition of 2,4,6-triphenylpyrylium salt to η3-phosphine PR3 (R＝Me, Et, Ph) afforded novel trisubustituted (1,3,5-triphenyl-4-trisubstituted phosphoranylidene-5-one) phosphonium perchlorates (1) in good yields. All products were fully characterized by 1H NMR, 13C NMR, 31P NMR, MS techniques and elemental analyses.

Key words: η3-phosphine, conjugated addition, pyrylium salt, phosphonium salt
