The front cover picture , provided by Qing‐Wen Song and Liang‐Nian He, illustrates a silver‐catalyzed carboxylative cyclization of propargylic alcohols/propargylic amines with CO 2 for the synthesis of α ‐alkylidene cyclic carbonates/oxazolidinones under ambient conditions without employing any additional organic base and ligand. The synergistic effect of Lewis basic and Lewis acidic species in conjunction with the bulkier counterion, via the alkyl carbonate intermediate, leads to the excellent efficiency. The picture shows an outline of exhaust gas and chemical conversion via a sustainable CO 2 recycling process into value‐added products using a green catalytic method. Details can be found in the full paper on pages 1251–1258 (Q.‐W. Song and L.‐N. He, Adv. Synth. Catal. 2016 , 358 , 1251–1258; DOI: 10.1002/adsc.201500639 ).
