Diazo - Wikipedia
In organic chemistry, the diazo group is an organic moiety consisting of two linked nitrogen atoms at the terminal position. Overall charge-neutral organic compounds containing the diazo group bound to a carbon atom are called diazo compounds or diazoalkanes[a] and are described by the general structural formula R2C=N+=N−.

2023年3月17日 · Nature Communications - The difunctionalization of diazo compounds, traditionally with one nucleophile and one electrophile, is a powerful strategy. Here, the authors develop a path of...
Iodine-catalyzed diazo activation to access radical reactivity
2018年5月17日 · Herein, we report our discovery of iodine-catalyzed diazo activation and application of this method toward olefin cyclopropanation (Fig. 1b). Importantly, this method revealed a metal-free...
Here, we review the use of diazo compounds in chemical biology. We begin with an overview of natural products and amino acids that contain a diazo group. That is followed by a summary of methods for the chemical synthesis of diazo compounds. We then highlight the remarkable versatility of diazo compounds in the context of chemical biology, and we
Isolation and characterization of diazoolefins | Nature Chemistry
2021年10月7日 · Here we show that diazoolefins are observed to form in reactions of N-heterocyclic olefins with nitrous oxide. The products benefit from resonance stabilization, which enables isolation on a...
