  • Telomerization of 1,3-butadiene with various alcohols by Pd/TOMPP catalysts: new opportunities for catalytic biomass valorization

    The telomerization of 1,3-butadiene with various alcohols has been investigated using a catalyst based on a Pd(acac)2 precursor and a phosphine ligand, TOMPP (TOMPP = tris-(o-methoxyphenyl)phosphine). We were able to demonstrate the capability of the catalyst to telomerize 1,3-butadiene with various multifunctional nucleophiles having primary and secondary alcohol functions. High yields of telomer products (>98%) were obtained in very short reaction times (<2 h). The telomerization activity and selectivity of the Pd/TOMPP complex was strongly influenced by the type of alcohol used as substrate. When diols were used, telomerization of 1,3-butadiene with 1,2-propanediol and 1,2-butanediol afforded the highest yield of mono-telomer (over 70%) and for 1,2-butanediol a turnover frequency (TOF) of 300 000 h−1 was reached, combined with a turnover number (TON) of 7800.
    使用基于Pd(acac)2前体和配体TOMPP(TOMPP = 三(邻甲氧基苯基)膦)的催化剂,研究了1,3-丁二烯与各种醇的调聚反应。我们证明了该催化剂具有将1,3-丁二烯与具有伯醇和仲醇功能的多功能亲核试剂进行调聚的能力。在非常短的反应时间内(<2小时),获得了高产率的调聚产物(>98%)。Pd/TOMPP络合物的调聚活性和选择性受到所用醇类型的强烈影响。当使用二醇时,1,3-丁二烯1,2-丙二醇1,2-丁二醇的调聚反应获得了最高的一调聚物产率(超过70%),而对于1,2-丁二醇,达到了300,000 h−1的转化频率(TOF)和7800的转化数(TON)。
  • Telomerization of 1,3-butadiene with highly substituted alcohols using Pd/NHC-catalysts — Structure-reactivity-relationship of the O-nucleophile

    alcohols could clearly be attributed to electronic properties, along with steric hindrance. Furthermore, the influence of double bonds in the alcohol chain has been studied. Interestingly, alcohols with double bonds that are not conjugated to the hydroxyl groups were shown to be more active than saturated alcohols. Allylic alcohols, however, are significantly less reactive than their saturated analogs
    摘要 1,3-丁二烯与醇的催化调聚反应是一种催化反应,是根据醇底物合成不同特性的2,7-辛二烯醚的有效工具。虽然对 Pd/膦型催化剂进行了深入研究,但在调聚反应中几乎只与甲醇一起研究了高活性 Pd/NHC(=N-杂环卡宾)催化剂。在使用来自可再生能源的醇(例如木质素纤维素或萜烯等)的过程中,需要更深入地了解这些催化剂的反应性。在这项工作中,我们对不同链长的直链和支链醇进行了综合研究。发现了伯醇和仲醇之间反应行为的不同趋势,并且仲醇的较低反应性可以清楚地归因于电子特性以及空间位阻。此外,还研究了醇链中双键的影响。有趣的是,具有未与羟基共轭的双键的醇显示出比饱和醇更具活性。然而,烯丙醇的反应性明显低于其饱和类似物。通过收集到的信息,我们能够推断出某些官能团和取代模式的结构反应性关系。这些发现通过使用萜醇获得新的烯丙基萜醇醚得到证实。已经研究了醇链中双键的影响。有趣的是,具有未与羟基共轭的双键
