    钛环丁烯或钛乙烯基卡宾配合物?γ-氯烯丙基硫化物与二茂钛(II)试剂反应生成的有机钛物种的反应活性。
    摘要:
    研究了用钛茂(II)试剂[Cp(2)Ti {P(OEt)(3)}(2)还原γ-氯烯丙基硫化物生成的有机钛物种的反应性。由α-单取代的γ-氯烯丙基硫化物形成的有机钛物质与1,5-二苯基戊-3--3-酮和苯乙烯反应生成共轭二烯和乙烯基环丙烷作为主要产物,因此表明形成了乙烯基卡宾配合物作为中间体。相反,由无环β,γ-二取代的γ-氯烯丙基硫化物生成的有机钛物种显示出钛环丁烯样的反应性,并且它们与1,5-二苯基戊烷-3-one的反应生成了均烯丙基醇。这些有机钛物质不与苯乙烯反应,但与二氯苯基膦反应得到磷环丁烯。在β-单取代,γ-单取代和α,γ-二取代的γ-氯烯丙基硫化物的情况下,有机钛物质与1,5-二苯基戊-3--3-酮和苯乙烯反应。前者反应产生均烯丙基醇,后者反应产生乙烯基环丙烷或未共轭的二烯。这些结果表明,钛环丁烯和/或钛乙烯基卡宾配合物是通过γ-氯烯丙基硫化物的还原钛化反应生成的,具体取决于它们的取代方式。

    A calcium-catalyzed direct substitution of π-activated alcohols with different organosilanes under very mild reaction conditions is presented. The high reactivity of the calcium catalyst allows efficient conversion of secondary and tertiary allylic, secondary benzylic, and tertiary propargylic alcohols with allyltrimethylsilane at room temperature. Furthermore, the first direct substitution of an alcohol

  • Metal-Free and Recyclable Route to Synthesize Polysubstituted Olefins<i>via</i>CC Bond Construction from Direct Dehydrative Coupling of Alcohols or Alkenes with Alcohols Catalyzed by Sulfonic Acid-Functionalized Ionic Liquids
    作者:Feng Han、Lei Yang、Zhen Li、Yingwei Zhao、Chungu Xia
    DOI:10.1002/adsc.201301150
    日期:2014.8.11
    AbstractA direct synthesis of polysubstituted olefins via construction of CC bonds, which involves the direct dehydrative coupling of alcohols or alkenes with alcohols, was realized using a series of alkanesulfonic acid group‐functionalized ionic liquids (SO3H‐functionlization ILs) without additives. The metal‐free and recyclable catalyst system avoided the disposal and neutralization of acidic catalysts after reaction and tolerated a broad range of substrates, including benzylic, allyl, propargylic, aliphatic and aromatic or aliphatic olefins. Additionally, the catalytic system was suitable for a gram‐scale preparation. Preliminary mechanistic studies indicated that the CH bond cleavage in this reaction might be involved in the rate‐determining step.magnified image
