  • Process for the preparation of urethanes
    申请人:Jacob Andreas
    公开号:US20090275771A1
    公开(公告)日:2009-11-05
    Urethanes are prepared by oxidative carbonylation of at least one amino compound in the presence of carbon monoxide, oxygen and organic, at least one hydroxyl-group-carrying compound. The carbonylation is carried out in the absence of halogen-containing promoters. The carbonylation is also carried out in the presence of a metal complex catalyst which contains neutral bidentate N-chelate ligands of the (N˜N) type, two monoanionic N,O-chelate ligands of the general type (N˜O) − or tetradentate dianionic chelate ligands (O˜N˜N˜O) 2− .
    聚氨酯是通过氧化羰基化至少一种氨基化合物来制备的,在碳一氧化碳、氧气和有机物存在下,至少还有一种带有羟基的化合物。羰基化是在不存在含卤素的促进剂的情况下进行的。羰基化也是在含有中性双齿N-螯合配体(N˜N)类型的金属络合物催化剂存在下进行的,这种配体是两个单负离子N,O-螯合配体的一般类型(N˜O) − 或四个双负离子螯合配体(O˜N˜N˜O) 2− 。

  • CATALYST FOR PRODUCING N-SUBSTITUTED CARBAMATES, AND THE PREPARATION AND APPLICATION OF THE SAME
    申请人:Wershofen Stefan
    公开号:US20100298592A1
    公开(公告)日:2010-11-25
    The present invention relates to a novel catalyst for producing N-substituted carbamates, the preparation of the catalyst and an improved method for producing N-substituted carbamates from these novel catalysts. The active component of the catalyst is a heteropoly acid and the catalyst support comprises a metal oxide or a metalloid oxide. The catalyst can be used to promote the reaction of carbamate and amine, thereby generating N-substituted carbamates with high yield. In the presence of the catalyst, the reaction conditions are relatively mild, the catalytic activity and selectivity of the reaction are high, and the reaction time is relatively short. Furthermore, the catalyst can be conveniently separated from the reaction system and recycled. therefore, the catalyst can be used to facilitate the further scale-up test and commercial application.
    本发明涉及一种用于生产N-取代氨基甲酸酯的新型催化剂,包括催化剂的制备和从这些新型催化剂生产N-取代氨基甲酸酯的改进方法。催化剂的活性成分是杂多酸,催化剂载体包括金属氧化物或金属氧化物。催化剂可用于促进氨基甲酸酯和胺的反应,从而高产率地生成N-取代氨基甲酸酯。在催化剂存在的情况下,反应条件相对温和,反应的催化活性和选择性高,反应时间相对较短。此外,催化剂可以方便地从反应体系中分离并回收。因此,该催化剂可用于促进进一步的放大试验和商业应用。

    作者:Antonella Dalla Cort、José Ignacio Miranda Murua、Chiara Pasquini、Miquel Pons、Luca Schiaffino
    DOI:10.1002/chem.200400016
    日期:2004.7.5
    A novel member of a new class of chiral uranyl-salophen complexes has been synthesised. The chiral recognition ability of this receptor toward the enantiomers of two primary amines, a sulfoxide, and a quaternary ammonium chloride has been evaluated for the first time. The enantioselectivities obtained are encouraging. The NMR method developed for this purpose allows a fast, quantitative determination
    合成了一类新的手性铀酰-salophen复合物的新型成员。首次评估了该受体对两种伯胺,亚砜和氯化季铵的对映体的手性识别能力。获得的对映选择性是令人鼓舞的。为此目的开发的NMR方法可直接从其外消旋混合物中快速,定量地确定宿主的对映选择性,并可作为应用组合方法寻找新受体的初步筛选工具。在这种情况下进行的实验还表明,这种手性铀酰-salophen受体的外消旋化的激活屏障远高于先前报道的21 kcal mol(-1)的下限。
