  • The preparation of the 2,4-di(t-butyl)pentadienyl anion and its Ti(II), Cr(II), and Zn(II) complexes
    作者:Richard D. Ernst、Jeffrey W. Freeman、Paul N. Swepston、David R. Wilson

    日期:1991.1
    The potassium of the 2,4-di(t-butyl)pentadienyl anion may be prepared by metallation of the corresponding 1,3-diene. This anion reacts readily with titanium, chromium, and zinc dichloride complexes to yield the appropriate M[2.4-(t-C4H9)2C5H5]2 species, which display significant differences relative to their 2,4-dimethylpentadienyl analogs.

  • Reactions of Alkylthio Derivatives of Aluminum with Aldehydes, Ketones, and Olefins
    作者:J. M. Lalancette、Y. Beauregard、M. Bhéreur
    DOI:10.1139/v71-497
    日期:1971.9.15

    The preparation of ((CH3)2CHS)2AlCH3 and (t-CaH9S)2AlCH3 is reported. The reactions of (RS)2AlCH3 (R = CH3, (CH3)2CH, t-C4H9) with ketones give aldol condensations leading to the corresponding conjugated ketones, with the acetyl group R—CO—CH3; with other ketones, a mixture of thioacetal and enolthioether is obtained. With aldehydes, a mixture of thioacetal and enolthioether is observed. With olefins there is an addition of two RS groups on the site of the double bond, with a small percentage of allylic substitution. With conjugated ketone, the saturated ketone is obtained with the alkylthio group in β position. All those reactions proceed with good yields and appear quite general.

    (CH3)2CHS)2AlCH3和(t-C4H9S)2AlCH3的制备已报道。(RS)2AlCH3 (R = CH3, (CH3)2CH, t-C4H9)与酮的反应产生醛缩反应,形成相应的共轭酮,带有乙酰基R—CO—CH3;与其他酮反应,得到硫缩醛和烯硫醚的混合物。与醛反应,观察到硫缩醛和烯硫醚的混合物。与烯烃反应,双键位置上发生两个RS基团的加成,少量的烯丙基取代。与共轭酮反应,饱和酮在β位得到烷硫基。所有这些反应都具有良好的产率,并且似乎相当普遍。

The exo-anti isomer structure of 22 has unequivocally been established by an X-ray diffraction study. The analogous rhodium exo-syn isomer [Cp*Rh(η3-CH2C(Me)CHC(Me)O)(NCMe)][BF4] (23) has been established by 1H and 13C NMR spectroscopy. Exo-anti and exo-syn preferences have been established for
