The Cover Feature shows a figurative synthesis of alkenyl boronates via hydroboration of alkynes with boranes in the presence of a Ru−H catalyst conducted in supercritical CO 2 (scCO 2 ) under repetitive batch mode. In their Full Paper, J. Szyling et al. describe the application of scCO 2 as a solvent and extractant in the repetitive batch hydroboration, using a self‐dosing Ru−H catalyst, which is gradually released to the reaction mixture under supercritical conditions. The strategy is a sustainable and green manner to obtain boryl‐substituted olefins (easily extracted in scCO 2 ) with high yields and selectivities up to the 16th catalytic cycle. More information can be found in the Full Paper by J. Szyling et al. on page 531 in Issue 3, 2018 (DOI: 10.1002/cctc.201701318).
