  • A New Type of Carbonylation of Styrenes Catalyzed by Pd(OAc)<sub>2</sub>Combined with Molybdovanadophosphate
    作者:Shingo Yamada、Yasushi Obora、Satoshi Sakaguchi、Yasutaka Ishii
    DOI:10.1246/bcsj.80.1194
    日期:2007.6.15
    A new type of carbonylation of styrenes was achieved under a 1:1 mixture of CO (0.5 atm) and O2 (0.5 atm) in the presence of Pd(OAc)2 combined with H5PMo10V2O40·nH2O to give 4-methyl-2-phenylnaphthalen-1(4H)-one in 78% yield. Various substituted styrenes were also carbonylated to the corresponding substituted arylnaphthalen-1(4H)-ones in moderate yields. The reaction was found to proceed in two stages involving the head-to-tail dimerization of styrenes, followed by carbonylation of the resulting dimers. Styrenes were efficiently dimerized under air (1 atm) in the absence of CO even at room temperature to produce head-to-tail dimers in good yields.
    一种新型的苯乙烯羰基化反应在1:1的CO(0.5 atm)和O2(0.5 atm)混合气氛中进行,借助Pd(OAc)2与H5PMo10V2O40·nH2O的结合,可以以78%的产率得到4-甲基-2-苯基萘-1(4H)-酮。还对多种替代的苯乙烯进行了羰基化反应,得到相应的替代芳基萘-1(4H)-酮,且产率适中。研究发现,该反应分为两个阶段:首先是苯乙烯的头尾二聚化,随后是生成的二聚体的羰基化。在没有CO的情况下,即使在室温下,苯乙烯也能在空气(1 atm)中高效二聚,形成头尾二聚体,并且产率良好。
  • Triflic Acid/Silane Promoted Deoxygenative Transformation of Ketones via Carbocations

    serve as a cooperative reductant to transform ketones via carbocations that undergo β-H elimination much faster than hydride transfer from silane to produce alkenes with high selectivity. Alternatively, the presence of indoles would incept the protonated ketones to generate carbocations, allowing access to Csp2–Csp3 bond formation with high reactivity and selectivity in “one pot”.
    将酮脱氧转化为增值产品通常会受到贵金属催化剂或复杂操作条件的影响。三氟甲磺酸和硅烷作为协同还原剂,通过碳正离子转化酮,碳正离子的β-H消除速度比硅烷的氢化物转移速度快得多,从而高选择性地生产烯烃。或者,吲哚的存在会引发质子化酮产生碳正离子,从而在“一锅”中形成具有高反应性和选择性的Csp 2 -Csp 3键。
  • Chemoselective hydroamination of vinyl arenes catalyzed by an NHC-amidate-alkoxide Pd(II) complex and p-TsOH
    作者:Richard Giles、Justin O’Neill、Joo Ho Lee、Michael K. Chiu、Kyung Woon Jung

    日期:2013.7
    The hydroamination of various substituted vinyl arenes with benzenesulfonamide was explored using an NHC-amidate-alkoxide palladium catalyst in conjunction with p-TsOH. Utilizing halide-substituted and electron-rich vinyl arenes, this methodology selectively furnished the cross-coupled hydroamination products in moderate to excellent yields in a Markovnikov fashion while greatly reducing undesired acid-catalyzed homocoupling of the vinyl arenes. Electron-rich vinyl arenes typically required milder conditions than electron-poor ones. While most effective for para-substituted substrates, the catalyst system also furnished the desired products from ortho- and meta-substituted vinyl arenes with high chemoselectivities.

    and transition-metal-free strategy for the synthesis of thiophenes from substituted buta-1-enes with potassium sulfide has been presented. The reaction achieves double C–S bond formations via cleavage of multiple C–H bonds and provides an efficient approach to access various functionalized thiophenes. Moreover, the strategy can also be used for the synthesis of thiophenes from 1,4-diaryl-1,3-dienes.
