合成了一系列苄基型季鏻盐,利用它们与对氯苯甲醛在不同碱(其它条件相同)下的Wittig反应,探讨了阴离子对Wittig反应立体化学的影响,结果表明阴离子效应与碱有关,并讨论了阴离子的作用。
A series of benzyl-type quaternary phosphonium salts were synthesized. The Wittig reaction of p-chlorobenzaldehyde with different bases (other conditions being the same) was used to investigate the influence of anions on the stereochemistry of Wittig reaction. The results showed that the anion effect was related to the base, And discussed the role of anions.
