  • Cation-Exchanged Montmorillonite (M<sup><i>n</i>+</sup>-Mont)-Catalyzed Prins Reaction
    作者:Jun-ichi Tateiwa、Keiji Hashimoto、Takayoshi Yamauchi、Sakae Uemura
    DOI:10.1246/bcsj.69.2361
    日期:1996.8
    The Prins reaction of styrenes with paraformaldehyde or 1,3,5-trioxane in toluene in the presence of cation-exchanged montmorillonite (Mn+-mont), which worked as a Brønsted acid catalyst, at 80 °C produced 4-aryl-1,3-dioxanes selectively in up to 99% isolated yield with a turnover number of up to 5.9 × 102. Among the examined 21 Mn+-monts, Ce3+- and Fe3+-monts were revealed to be quite effective. Regeneration of the catalyst was confirmed with the Ce3+-mont, which could be effectively recycled at least three times. Many lanthanide metal ion-exchanged montmorillonites (Ln3+-monts) were prepared and characterized by X-ray powder diffraction (XRD) and temperature-programmed desorption of ammonia gas (NH3-TPD) methods.
    在甲苯中,使用阳离子交换蒙脱石(Mn+-mont)作为布朗斯台德酸催化剂,在80°C下,苯乙烯与三聚甲醛或1,3,5-三氧六环进行普林斯反应,能够选择性地生成4-芳基-1,3-二氧六环,最高分离收率达99%,转化数高达5.9×102。在考察的21种Mn+-mont中,铈(III)和铁(III)蒙脱石显示出较高的效果。催化剂的再生性通过铈(III)蒙脱石得到证实,它至少可以有效地循环使用三次。许多镧系金属离子交换的蒙脱石(Ln3+-monts)通过X射线粉末衍射(XRD)和程序升温氨气脱附(NH3-TPD)方法制备并表征。

    日期:2021.12.15
    Despite their significant potential, catalytic asymmetric reactions of olefins with formaldehyde are rare and metal-free approaches have not been previously disclosed. Here we describe an enantioselective intermolecular Prins reaction of styrenes and paraformaldehyde to form 1,3-dioxanes, using confined imino-imidodiphosphate (iIDP) Brønsted acid catalysts. Isotope labeling experiments and computations
    尽管它们具有巨大的潜力,但烯烃与甲醛的催化不对称反应是罕见的,并且以前没有公开过不含金属的方法。在这里,我们描述了苯乙烯和多聚甲醛的对映选择性分子间 Prins 反应以形成 1,3-二恶烷,使用受限的亚氨基-亚氨基二磷酸 ( i IDP) 布朗斯台德酸催化剂。同位素标记实验和计算表明酸活化甲醛低聚物向烯烃中的协同、高度异步添加。对映体富集的 1,3-二恶烷可以转化为相应的光学活性 1,3-二醇,它们是有价值的合成构件。

    The sterically congested Lewis acid 1 was used as a catalyst in the Prins reaction of various styrenes and formaldehyde. 4-Aryl-1,3-dioxanes 5 were selectively formed as the exclusive products of the reaction with styrenes 4a-i and vinylthiophenes 4j-k. The reaction proceeded in most cases with good to excellent yields (55-99%). Styrenes which carried a strongly electron-withdrawing group (CN. CO 2

  • Novel Hydrophobic Brønsted Acidic Ionic-liquids as Efficient and Reusable Catalysts for Organic Reactions in Water

    日期:2006.10
    Novel hydrophobic Brønsted acidic ionic liquids (HBAIL) were prepared and utilized as acid catalysts in organic reactions in water. HBAILs were demonstrated, for the first time, to be effective catalysts for Prins cyclization of styrene derivatives in water with a formaldehyde water solution. Many styrene derivatives could be successfully converted to the corresponding 1,3-dioxanes. Other dehydration reactions also proceeded well using HBAILs in water. After reactions, HBAILs could be easily recovered and reused without significant loss of activity.
