Treatment of benzylic bromides with Zn and LiCl, followed by the reaction with i-butyl nitrite gave N-arylmethyl-N-arylmethyleneamine N-oxides in moderate yields. The present reaction is a novel and simple method for the preparation of nitrones from benzylic bromides, although the yields are moderate.
direct liquefaction of lignite in a syngas (CO + H2) system. In this study, anthracene was utilized as a polycyclic model compound of lignite, to which hydrogen is donated by the H2/D2 producedfrom CO and H2O/D2O via the WGSR. The results show that the model compound of the polycyclic aromatic hydrocarbon in coal (anthracene) undergoes partial cracking and polycondensation under non-hydrogen-donor conditions
水煤气变换反应 (WGSR) 是褐煤在合成气 (CO + H 2 ) 系统中直接液化的关键反应。在这项研究中,蒽被用作褐煤的多环模型化合物,由 CO 和 H 2 O/D 2产生的 H 2 /D 2向其提供氢气O 通过 WGSR。结果表明,煤中多环芳烃模型化合物(蒽)在400℃无供氢条件下发生部分裂化和缩聚反应。此外,NiO催化的WGSR可以产生氢气用于蒽的加氢。通过同位素标记将氘代产物与常规加氢产物的质谱图进行比较,发现甲苯、1,4-二甲苯、甲基萘、1,1-二苯基乙烯、甲基蒽等化合物的烷基侧链位置容易发生氘化,可以进行推测蒽的主要加氢路线,为褐煤在合成气(CO + H 2)系统中直接液化催化加氢提供了理论支持。
