This work presents an acid-free method for aromatic nitrosation using 2-methoxyethyl nitrite (MOE-ONO). While originally developed as a NOx radical source in our group, we demonstrate the utility of MOE-ONO as a NO cation source for aromatic electrophilic nitrosation. This method successfully nitrosates phenols, naphthols, and other pronucleophiles, completely suppressing undesired nitration by NOx radicals. Notably, it enables nitrosation of acid-sensitive substrates, which has been difficult to achieve with existing protocols.

使用亚硝酸 2-甲氧基乙酯作为 NO 阳离子源的直接芳香亚硝化



这项工作提出了一种使用亚硝酸 2-甲氧基乙酯 (MOE-ONO) 进行芳族亚硝化的无酸方法。虽然我们小组最初开发的是 NO x自由基源,但我们证明了 MOE-ONO 作为芳香族亲电亚硝化的 NO 阳离子源的实用性。该方法成功地将苯酚、萘酚和其他亲核试剂亚硝化,完全抑制 NO x自由基引起的不需要的硝化。值得注意的是,它能够实现酸敏感底物的亚硝化,这是现有方案难以实现的。
