The Cover Feature shows the environmentally benign N‐formylation of various amines over a TiO 2 ‐supported gold nanoparticle catalyst using CO 2 as the carbonyl source under a H 2 atmosphere. In their Communication, T. Mitsudome et al. demonstrate that the gold catalyst is highly selective in the formylation of amines bearing reducible functional groups, whereas functional groups such as olefins, halogens, carbonyls, carbamates and cyano moieties are left intact during the reaction under H 2 atmosphere (>99% selectivity). The catalyst is reusable without any loss of activity or selectivity. The high selectivity is attributed to the cooperative catalysis between gold nanoparticles and TiO 2 . More information can be found in the Communication by T. Mitsudome et al. on page 3632 in Issue 19, 2017 (DOI: 10.1002/cctc.201700726).
