diisopropylanmine

Preparation of supported Pd-La/Al2O3 catalyst and its catalytic prope rties in the preparation of 2,6-diisopropyl aniline (2,6-DIPA) by gas-phase am in ation of 2,6-diisopropylphenol(2,6-DIPP) were investigated.

研究了负载型Pd-La/Al2O3催化剂的制备条件及其在2,6-二异丙基苯酚(2,6-DIPP)气相胺化制备2,6-二异丙基苯胺中的反应性能。

The epimerization of methylphenidate derivative with active α -proton under lithium diisopropylamine (LDA) was explored.

在制备治疗滥用可卡因症的药物———(±) threo 哌醋甲酯衍生物中,发现了含α活泼氢的哌醋甲酯衍生物在二异丙基胺锂作用下的差向异构化作用,(±) erythro 哌醋甲酯经过乙酰基化、二异丙基胺锂作用关环后,生成热力学上更稳定的threo构型产物,产物构型通过1HNMR和13CNMR得到了确认,探讨了该过程的反应机理。
