【摘要】 研究以N,N-二甲基乙二胺、苯甲胺和环己胺为基体,先制备出相应的脂肪双胺化合物,再和(C5H5)3La(THF)组装出三个脂肪双胺稀土金属配合物.通过使用该脂肪双胺稀土金属配合物作为催化剂对CH3NO2和C6H5CHO的反应进行研究,从催化反应时间、反应温度和催化剂用量为依据对均配型稀土金属配合物进行评价,减少Henry反应过程中的副反应,提高产率,为Henry反应制备β-硝基醇及其衍生物提供合理的理论参考.更多还原

【Abstract】 In this study,N,N-two methyl ethylenediamine,benzylamine and cyclohexylamine were used as substrates,the corresponding fatty diamines were prepared,and then three fatty diamide rare earth complexes were assembled with( C5 H5)3 La( THF). By using the double fatty amine rare earth metal complexes as catalysts for CH3 NO2 and C6 H5 CHO reaction were studied from the catalytic reaction time,reaction temperature and catalyst dosage on the basis of both with the type of rare earth metal complexes were evaluated,reduce adverse reaction,Henry reaction in the process of improving the yield,with beta nitro alcohol and its derivatives scientific theoretical reference for Henry reaction preparation.更多还原
