arylnitromethanes and nitrite esters. A modified approach for the isolation of arylnitromethanes is described, which represents a valuable improvement of the established Victor Meyer reaction. The isolation technique, which involves reaction of the nitrite ester with urea in methanol, allows the desired arylnitromethanes to be isolated, without loss, in 29–75% yields, and generates the corresponding recyclable
易于获得且稳定的环甲氧基化苄基氯与 AgNO2 反应生成相应的芳基硝基甲烷和亚硝酸酯的混合物。描述了一种改进的芳基硝基甲烷分离方法,它代表了对已建立的 Victor Meyer 反应的有价值的改进。该分离技术涉及亚硝酸酯与脲在甲醇中的反应,可以以 29-75% 的收率无损失地分离出所需的芳基硝基甲烷,并生成相应的可回收苯甲醇。出乎意料的是,环甲氧基化苄基碘不能使用,因为它们不够稳定并且在开发的反应条件下会产生焦油。
