An unusual cascade annulation of arynes with N-alkyl-N-nitrosamides is developed by leveraging aryne σ-insertion and C(sp3)-H bond functionalization strategies under transition-metal-free conditions at ambient temperature, offering functionalized indazoles in high yields and regioselectivity. The protocol is scalable and exhibits a broad substrate scope. The reaction mechanism is also studied with DFT calculations.

A methodology for the oxidative amidation of aldehydes to yield N-acyl azoles is reported. The approach employs sodium persulfate and a catalytic amount of a nitroxide and is applicable to a range of structurally diverse substrates.

The base-catalyzed reactions of p-fluorobenzoyl chloride provide a convenient method for (19)F NMR analysis of alcohols, phenols, carboxylic acids, amines, and thiols.The (19)F chemical shift and yield data for p-fluorobenzoyl derivatives for nearly 100 compounds are presented.The yield data for these p-fluorobenzoyl derivatives suggest a simple, and in many cases, quantitative method for introducing a fluorine tagging group.The (19)F chemical shifts indicate a wide chemical shift range (ca. 10 ppm) for a large number of compounds.Furthermore, most chemical classes (e.g., phenols, alcohols, etc.) have fairly well resolved chemical shift regions.
