    The photolysis of pyrazolenines normally gives cyclopropenes via a vinyldiazoalkane; but, in the present work 3-(1′-acyloxyalkyl)-5,5-dimethylpyrazolenines have been found to give allene and 1,3-diene esters in good yield, together with small quantities of a vinylallene. Attempts to trap an intermediate diazoalkene by photolysis in the presence of acid were not successful, leading merely to partial
    吡唑啉的光解反应通常通过乙烯基重氮烷烃生成环丙烯。但是,在目前的工作中,发现3-(1'-酰氧基烷基)-5,5-二甲基吡唑腈与少量的乙烯基烯丙基烯能以良好的产率得到烯丙基和1,3-二烯酸酯。尝试在酸存在下通过光解来捕获中间重氮烯烃是不成功的,仅导致产物中酰氧基的部分随机化。已经对随机化程度进行了定量研究,其结果与涉及分子间和分子内过程的离子机制相符,并且在某些方面与建议的氮热分解机理相似。-亚硝基酰胺。建议了一条可能的通向乙烯基碳离子的一般路线。
  • Simpler and Cleaner Synthesis of Variously Capped Cobalt Nanocrystals Applied in the Semihydrogenation of Alkynes

    synthesis is performed at room temperature in the presence of ecofriendly fatty alcohols to passivate Co NCs. Through a recycling step, the yield of Co NCs is improved and the waste generation is limited, making this synthetic route cleaner. After an easy exchange of the capping ligands, we applied them as unsupported catalysts in the stereoselective semihydrogenation of alkynes.
    与经典的有机金属方法不同,我们在此报告一种合成途径,不需要还原源或加热即可产生均质的六方密堆积钴纳米晶体(Co NCs)。涉及歧化过程,这种简单,快速(6分钟)的合成是在室温下,在环境友好的脂肪醇存在下钝化Co NCs的过程中进行的。通过回收步骤,可提高Co NCs的产量,并减少废物产生,从而使这种合成路线更清洁。在轻松更换封端配体后,我们将它们用作炔烃的立体选择性半氢化反应中的非负载型催化剂。

    The asymmetric dihydroxylation (AD) of tertiary allylic alcohols is examined. Good to excellent ee's are obtained with trans-di- and tri-substituted tertiary allylic alcohols of different substitution patterns except for a trisubstituted case where the tertiary carbinol substituent is on the disubstituted olefinic carbon.
