The Cover Feature shows a structurally well‐defined platinum complex bearing a bulky “supersteric” N‐heterocyclic carbene (NHC) ligand. This complex catalyzes the regio‐ and stereoselective dimerization of terminal acetylenes, whereas the analogues with sterically less‐hindered NHC ligands cannot promote the process. In their Communication, P. Żak et al. demonstrate that changes in the steric properties of the NHC ligand may drastically affect the catalytic properties of the corresponding complexes and generate new reactivity. More information can be found in the Communication by Żak et al. on page 3627 in Issue 19, 2017 (DOI: 10.1002/cctc.201700580).

封面文章：带有大容量N-杂环碳配体的铂络合物是末端炔烃完全选择性二聚的高效催化剂（ChemCatChem 19/2017）

封面特征显示了结构清晰的铂络合物，带有庞大的“超立体” N-杂环卡宾（NHC）配体。该复合物催化末端乙炔的区域和立体选择性二聚化，而在空间上受阻的NHC配体类似物不能促进这一过程。在他们的交流中，P。Żak等人。证明了NHC配体的空间性质的变化可能会极大地影响相应配合物的催化性质并产生新的反应性。informationak等人在《通讯》中可以找到更多信息。就在第19期，2017年3627页（：10.1002 / cctc.201700580 DOI）。
