Find and destroy: A series of oximes were constructed to simultaneously detect and detoxify organophosphorus‐based nerve agents. They function as optical sensors employing the oxime reactivity and incorporating a β‐hydroxyl group to undergo an intramolecular cyclization from the intermediate oxime–organophosphorus species. The generated isoxazole produces an enhanced fluorescent signal that reports
An efficient synthetic method for the synthesis of diazonaphthoquinones from naphthols is described. A variety of diazonaphthoquinones were synthesized from the corresponding naphthols by the diazo transfer with 2-azido-1,3-dimethylimidazolinium chloride prepared by the reaction of 2-chloro-1,3-dimethylimidazorinium chloride and sodium azide.
Various orthodiazonaphthoquinones (1-diazo-2(1H)-naphthalenones and 2-diazo-1(2H)-naphthalenones) were synthesized using the diazo-transfer reaction between the appropriate naphthol and 2-azido-1,3-dimethylimidazolinium chloride (ADMC). The ADMC was prepared by the reaction between 2-chloro-1,3-dimethylimidazolinium chloride and sodium azide. The diazo-transfer reaction selectively introduced the diazo group at the C(2) position of 1-naphthol or the C(1) position of 2-naphthol. The naphthalenediols that were tested, except for 1,3-naphthalenediol, also reacted with ADMC to afford the corresponding monodiazotized compound. X-ray analyses suggested that the diazonaphthoquinones did not have diazoniumnaphtholate structures but had diazocarbonyl structures.

novel and efficient [3 + 2] cycloaddition reaction of azaoxyallyl cations and 1,2-benzisoxazoles to give oxazoline derivatives has been developed. The transformation provides a rapid entry to functionalized oxazoline scaffolds under mild and transition-metal-free conditions, which will greatly expand the reaction types of heterocycle chemistry and pave the way for syntheses of bioactivecompounds.
