RT Journal Article T1 Transition Metal‐Promoted Reactions in Aqueous Media and Biological Settings A1 Destito, Paolo A1 Vidal Vides, Cristian A1 López García, Fernando A1 Mascareñas Cid, José Luis K1 Aqueous catalysis K1 Biocatalysis K1 Biological chemistry K1 Cellular chemistry K1 Organometallic catalysis AB During the last decade, there has been a tremendous interest for developing non‐natural biocompatible transformations in biologically relevant media. Among the different encountered strategies, the use of transition metal complexes offers unique possibilities due to their high transformative power. However, translating the potential of metal catalysts to biological settings, including living cells or small‐animal models such as mice or zebrafish, poses numerous challenges associated to their biocompatibility, and their stability and reactivity in crowded aqueous environments. Herein, we describe the most relevant advances in this direction, with a particular emphasis on the systems’ structure, their mode of action and the mechanistic bases of each transformation. Thus, the key challenges from an organometallic perspective might be more easily identified PB Wiley YR 2021 FD 2021 LK http://hdl.handle.net/10347/24848 UL http://hdl.handle.net/10347/24848 LA eng NO Destito, P.; Vidal, C.; and López, F.; Mascareñas, J.
