Two approaches for the synthesis of substituted phosphonium salts from easily available benzyl alcohols and their heterocyclic analogs have been developed. The developed protocols are complementary: the direct mixing of alcohol, trimethylsilyl bromide, and triphenylphosphine in 1,4-dioxane followed by heating at 80 °C was found to be more efficient for acid-sensitive substrates, such as salicyl or
已经开发了两种从容易获得的苯甲醇及其杂环类似物合成取代鏻盐的方法。所开发的方案是互补的:发现将醇、三甲基溴化甲硅烷和三苯基膦直接混合在 1,4-二恶烷中,然后在 80 °C 下加热对酸敏感底物(例如水杨醇或糠醇)更有效作为仲苯甲醇,而包括顺序添加三甲基甲硅烷基溴和三苯基膦的一锅法可以为带有电中性或吸电子取代基的苯甲醇提供更高的产率。
