Inside Back Cover: Sonochemically‐Induced Reduction of Alkenes to Alkanes with Ammonia (Angew. Chem. Int. Ed. 51/2022)

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.
