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
已经进行了不含碱、酸和催化剂的氢膦化反应,仅使用 2-甲基四氢呋喃作为添加剂。通过将二苯基膦添加到烯烃、单官能和多官能丙烯酸树脂(基于丙烯酸酯和甲基丙烯酸酯基体)和丙烯酰胺基材中,可以以良好至优异的产率获得一系列新的单、二、三和四膦化合物。将四当量的生物质衍生的 2-MeTHF 添加到反应介质中可以提高转化率和反应时间,并降低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,这种转化都显示出对反马尔科夫尼科夫产物的专有区域选择性。
