The inside back cover picture , provided by Lijin Xu and co‐workers, illustrates a new and efficient catalytic system consisting of [Cp*RhCl 2 ] 2 and 2,2′‐bipyridine (bpy) for transfer hydrogenation of a variety of quinoxalines, quinoxalinones, quinolines and indoles in aqueous solution with formate as the hydrogen source. The aqueous phase reduction is found to be highly pH‐dependent and acidic pH values are needed for optimal reduction. The new protocol is environmentally friendly and easy to conduct under mild conditions. Details can be found in the full paper on pages 3529–3537 (L. Zhang, R. Qiu, X. Xue, Y. Pan, C. Xu, H. Li, and L. Xu, Adv. Synth. Catal. 2015 , 357 , 3529–3537; DOI: 10.1002/adsc.201500491 ).
