    在六甲基二锡存在下区域选择性钯催化的亲电子烯丙基取代。
    摘要:
    [反应:请参见文字]。官能化的烯丙基氯和乙酸烯丙酯的钯催化亲电子烯丙基取代可以在温和的反应条件下在六甲基二锡存在下实现。取代反应在支链烯丙基末端具有很高的区域选择性。区域选择性串联双烯丙基化反应可以通过使用亚苄基亚甲基腈作为底物来进行。反应机理可以通过双烯丙基铝中间体的参与来解释。该反应的一个特别有趣的机理特征是钯在同一催化循环中催化多达三个不同的转化。DFT计算表明区域选择性是由烯丙基取代基在反应中间体的eta1-烯丙基部分中的位置决定的。

  • Palladium-Catalyzed Electrophilic Substitution of Allyl Chlorides and Acetates via Bis-allylpalladium Intermediates

    the application of neutral and mild reaction conditions. The substitution reaction occurs with very high regioselectivity at the branched allylic terminus. Moreover, in several reactions, a high stereoselectivity was observed indicating that this new catalytic process has a high potential for stereoselective synthesis. The regioselectivity of the reaction can be explained on the basis of DFT calculations
    官能化的烯丙基氯和乙酸烯丙酯的钯催化亲电子烯丙基取代可以在温和的中性反应条件下在六甲基二锡存在下实现。这种有效的一锅法涉及钯催化的瞬态烯丙基锡烷的形成,然后生成双烯丙基钯中间体,该中间体随后与亲电子试剂反应。使用这种催化转化,各种醛和亚胺可以被烯丙基化,从而提供高度官能化的均烯丙基醇和胺。此外,可以通过使用异氰酸甲苯酯和亚苄基亚甲基腈作为底物进行串联双烯丙基化反应。该反应的一个特别有趣的机理特征是钯在每个催化循环中催化多达三个不同的转化。由于采用中性和温和的反应条件,在催化反应中可以耐受各种烯丙基官能团,包括COOEt,CONH(2),COCH(3),CN,Ph和CH(3)。取代反应在支链烯丙基末端具有很高的区域选择性。此外,在几个反应中,观察到高的立体选择性,表明这种新的催化过程具有高的立体选择性合成潜力。反应的区域选择性可以基于DFT计算来解释。这些研究表明,烯丙基取代基优选反应中间体

    stannylation of allyl chloride, phosphonate, and epoxide substrates (4a-h) could be performed with hexaalkylditin reagents (3) under mild neutral reaction conditions. This catalytic reaction proceeds via palladium(II) intermediates without involvement of allyl-palladium complexes, and therefore the allylstannane product does not interfere with the palladium catalyst. Use of a combined catalytic system (1 + 2)

  • Streambank and vegetation response to simulated cattle grazing
    作者:Warren P. Clary、John W. Kinney
    DOI:10.1672/0277-5212(2002)022[0139:savrts]2.0.co;2
    日期:2002.3
    Simulated grazing techniques were used to investigate livestock impacts on structural and vegetation characteristics of streambanks in central Idaho, USA. The treatments, continued over two years, consisted of no grazing, simulated moderate early summer grazing, simulated moderate mid-summer grazing, and simulated heavy season-long grazing. The moderate treatments depressed the streambank surface about 3 cm, while the heavy season-long treatment resulted in an 11.5-cm depression. There were no differences between the no-grazing and moderate-grazing treatments for change in stream width, bank angle, bank retreat, or root biomass. The heavy season-long treatment, however, produced significant changes in these variables. The amount of foliage biomass (i.e., kg ha(-1)) removed by treatment was similar between the two years of study for the moderate treatments. The foliage removed from the heavy season-long treatment plots greatly decreased in the second year as plant growth decreased. Ten months after the last treatment application, the average spring foliage growth was 20-43% lower on the moderate treatment plots and 51-87% lower on the heavy season-long treatment plots than on the untreated control plots.
