Unprecedented Selectivity of Ruthenium Iodide Benzylidenes in Olefin Metathesis Reactions

摘要

Abstract > The development of selective olefin metathesis catalysts is crucial to achieving new synthetic pathways. Herein, we show that cis ‐diiodo/sulfur‐chelated ruthenium benzylidenes do not react with strained cycloalkenes and internal olefins, but can effectively catalyze metathesis reactions of terminal dienes. Surprisingly, internal olefins may partake in olefin metathesis reactions once the ruthenium methylidene intermediate has been generated. This unexpected behavior allows the facile formation of strained cis ‐cyclooctene by the RCM reaction of 1,9‐undecadiene. Moreover, cis ‐1,4‐polybutadiene may be transformed into small cyclic molecules, including its smallest precursor, 1,5‐cyclooctadiene, by the use of this novel sequence. Norbornenes, including the reactive dicyclopentadiene (DCPD), remain unscathed even in the presence of terminal olefin substrates as they are too bulky to approach the diiodo ruthenium methylidene. The experimental results are accompanied by thorough DFT calculations. </abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> <div class="translation abstracttxt"> <span class="zhankaihshouqi fivelineshidden" id="abstract"> <span>机译：</span><Abstract Type =“Main”XML：Lang =“en”> <标题类型=“main”>抽象</ title> > 选择性烯烃复分解催化剂的发展对于实现新的合成途径至关重要。在此，我们展示了这一点 cis </ i> -diodo /硫螯合钌苄基不与应变的环烯和内烯烃反应，但可以有效地催化末端二烯的复分解反应。令人惊讶的是，一旦产生了甲甲基中间体，内部烯烃就可以在烯烃复分解反应中分析。这种意外的行为允许紧张的面部形成 cis </ i> 通过1,9-氟烯的RCM反应的环CcTene。而且， cis </ i> -1,4-聚丁二烯可以转化为小循环分子，包括通过使用这种新序列的最小前体，1,5-环辛二烯。含有反应性二环戊二烯（DCPD）的冰片烯即使在末端烯烃基材的存在下也仍然毫杀，因为它们太大以接近二碘钌甲基甲基。实验结果伴随着彻底的DFT计算。 </ p> </摘要> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> </div> <div class="record"> <h2 class="all_title" id="enpatent33" >著录项</h2> <ul> <li> <span class="lefttit">来源</span> <div style="width: 86%;vertical-align: text-top;display: inline-block;"> <a href='/journal-foreign-19011/'>《Angewandte Chemie》</a> <b style="margin: 0 2px;">|</b><span>2020年第9期</span><b style="margin: 0 2px;">|</b><span>共5页</span> </div> </li> <li> <div class="author"> <span class="lefttit">作者</span> <p id="fAuthorthree" class="threelineshidden zhankaihshouqi"> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Nechmad Noy B.&option=202" target="_blank" rel="nofollow">Nechmad Noy B.;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Phatake Ravindra&option=202" target="_blank" rel="nofollow">Phatake Ravindra;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Ivry Elisa&option=202" target="_blank" rel="nofollow">Ivry Elisa;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Poater Albert&option=202" target="_blank" rel="nofollow">Poater Albert;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Lemcoff N.
