The reaction of tetranitromethane with B‐alkylcatecholboranes leads to the formation of unusual dinitrooxime ethers. A tentative mechanism is provided, which suggests the involvement of extremely fast addition of alkyl radicals to tetranitromethane. The substitution of one of the nitro groups in the oxime ethers by nucleophiles (such as secondary amines, halogens and styrene) and by radicals generated
四硝基甲烷与B-烷基儿茶酚硼烷的反应导致形成异常的二硝基肟醚。提供了一种尝试性机制,其暗示了将烷基极快地加成到四硝基甲烷中。据报道,肟醚中的一个硝基被亲核试剂(例如仲胺,卤素和苯乙烯)和由B-烷基儿茶酚硼烷生成的自由基取代。
