Abstract Red phosphorus reacts with 4-methoxystyrene in the KOH-DMSO superbase system (130 °C, 3 h, Ar) in the presence of a small quantity of H2O to give tris[2-(4-methoxyphenyl)ethyl]phosphane oxide as the main product in 30% yield. Microwave activation of the reaction (600 W, 6 min) affords basically a mixture of the phosphane oxide and tris[2-(4-methoxyphenyl)ethyl]phosphane (in a ratio of 1:1)
摘要 红磷在 KOH-DMSO 超强碱体系 (130 °C, 3 h, Ar) 中,在少量 H2O 存在下与 4-甲氧基苯乙烯反应生成三[2-(4-甲氧基苯基)乙基]氧化膦作为主要产品产率为30%。反应的微波活化(600 W,6 分钟)基本上提供了氧化膦和三[2-(4-甲氧基苯基)乙基]膦(比例为1:1)的混合物。当混合物暴露于空气中时(室温,24 小时),氧化磷以 85% 的产率形成。图形概要
