Nitrogen-centered radicals are versatile synthetic intermediates with the ability to undergo diverse reactions such as hydrogen atom transfer (HAT), β-scission, and addition across unsaturated systems. A long-standing impediment to the wider adoption of these intermediates in synthesis has been the difficulty of their generation. Herein we disclose a new hydrazonyl carboxylic acid precursor to nitrogen-centered
