在无碱、无酸、无催化剂的条件下,仅使用2-甲基四氢呋喃作为添加剂进行了氢化膦化反应。通过将二苯基膦加成到烯烃、单官能和多官能丙烯酸类(基于丙烯酸酯和甲基丙烯酸酯基序)和丙烯酰胺底物中,以良好至优异的产率获得了一个新的单-、二-、三-和四-膦化合物家族。向反应介质中加入4当量的生物质衍生的2-MeTHF改善了反应的转化率和时间,并降低了反应物对氧化的敏感性。这种简单,直接和原子经济的方法尊重绿色化学的原则。此外,在每种情况下,这种转化显示出对反马尔可夫尼科夫产物的排他性区域选择性。在无碱、无酸、无催化剂的条件下,仅使用2-甲基四氢呋喃作为添加剂进行了氢化膦化反应。
A hydrophosphination reaction that is free of base, acid and catalyst, using only 2-methyltetrahydrofuran as additive has been performed. A new family of mono-, di-, tri- and tetra-phosphines compounds are obtained in good to excellent yields by adding diphenylphosphine to alkenes, mono- and polyfunctional acrylics (based on acrylate and methacrylate motifs) and acrylamide substrates. Addition of four equivalent of bio-mass derived 2-MeTHF into the reaction media improves both conversion and time of the reaction and reduces the sensitivity of the reactants over oxidation. This simple, straightforward and atom-economic method respects the principles of Green Chemistry. Furthermore, in each case this transformation shows an exclusive regioselectivity towards the anti-Markovnikov products. A hydrophosphination reaction that is free of base, acid and catalyst, using only 2-methyltetrahydrofuran as additive has been performed.
