The Cover Feature shows the environmentally benign N‐formylation of various amines over a TiO₂‐supported gold nanoparticle catalyst using CO₂ as the carbonyl source under a H₂ 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 H₂ 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 TiO₂. 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).

封面功能：二氧化钛负载的金纳米颗粒催化剂，用于二氧化碳和氢气对官能化胺的选择性N甲酰化反应（ChemCatChem 19/2017）

封面功能显示了在H ₂气氛下，使用CO ₂作为羰基源，在TiO ₂负载的金纳米颗粒催化剂上，各种胺在环境上无害的N-甲酰化。在他们的交流中，T。Mitsudome等人。证明金催化剂在带有可还原官能团的胺的甲酰化中具有高度选择性，而在H ₂气氛下的反应过程中，诸如烯烃，卤素，羰基，氨基甲酸酯和氰基等官能团则完好无损（> 99％的选择性）。该催化剂是可重复使用的，而没有任何活性或选择性的损失。高选择性归因于金纳米颗粒与TiO ₂之间的协同催化作用。可以在T. Mitsudome等人的《通讯》中找到更多信息。就在第19期，2017年3632页（：10.1002 / cctc.201700726 DOI）。
