Over the last few decades, the fast-growing development of polymer supported reagents has led to the synthesis of a variety of reagents on solid support. Some of the major advantages of using such reagents are that they are less hygroscopic, easy to recover, and can be recycled. Here, we have demonstrated that in situ generated ethyl acrylate conjugated polystyryl-diphenylphosphine (PDPP–EA) derived from the reaction of a mixture of polystyryl-diphenylphosphine and ethyl acrylate in a stoichiometric ratio can efficiently catalyze the synthesis of β-nitroalcohols from the reaction of aldehydes and nitroalkanes under solvent-free conditions (SolFC).
在过去几十年中,聚合物支持试剂的快速发展导致了固体支持上合成各种试剂。使用这种试剂的一些主要优点是它们较少吸湿,易于回收,并且可循环利用。在这里,我们已经证明,在无溶剂条件下(SolFC),通过混合聚苯基二苯基膦和乙基丙烯酸酯在化学计量比下反应生成的乙基丙烯酸酯共轭聚苯基二苯基膦(PDPP-EA)可以有效催化醛和硝基烷烃的反应合成β-硝基醇。
