Résumé
The N−H bond of NH3 can be cleaved within cavitation bubbles, generated by ultrasonic irradiation at a high frequency, leading to the in situ formation of a diimide, which then induces the hydrogenation of alkenes, as reported by François Jérôme and co‐workers in their Communication (e202212719). Advantageously, this technique does not involve any transition metal and releases N2 as a sole coproduct.
