  • An efficient method for the preparation of 2,2,4-trisubstituted 1,2-dihydroquinolines using catalytic amount Bi(OTf)3 as catalyst
    作者:Zeynep Gültekin、Wolfgang Frey
    DOI:10.3998/ark.5550190.0013.822

    Substituted 1,2-dihydroquinolines have been synthesised from substituted anilines and methyl pyruvate using catalytic amounts of commercially available Bi(OTf)3 as a catalyst under microwave-assisted conditions. This method is simple, easy to work up, inexpensive, with a broad substrate scope and short reaction times. The reaction provides 1,2-dihydroquinolines (19 examples) in good yields (34-97%

    media has emerged as a new facet of green chemistry. In this paper, a sulfone‐containing imidazolium‐based Brønsted acid ionic liquid was prepared and used as a recyclable acid catalyst. The ionic liquid catalyst enables the use of an industrially acceptable and environmentally benign solvent, butyl acetate, as the reaction medium. The ionic liquid/butyl acetate biphasic system was successfully utilized
    用对环境有益的介质代替偶极和非质子传递溶剂已成为绿色化学的一个新方面。在本文中,制备了含砜的咪唑基布朗斯台德酸离子液体,并将其用作可循环利用的酸催化剂。离子液体催化剂能够使用工业上可接受且对环境无害的溶剂乙酸丁酯作为反应介质。离子液体/乙酸丁酯双相系统已成功用于许多有机反应中,这些反应通常严重依赖于偶极和非质子溶剂。
