Introduction Versatile, efficient, and stable precatalysts are crucial for advancing chemical reaction optimisation and discovery in fields such as cross-coupling and polymer chemistry. However, limited availability of such catalysts in specific areas has hindered new applications. We introduce a highly reactive, air- and moisture-stable ruthenium precatalyst, [(tBuCN)5Ru(H2O)](BF4)2, featuring an exchangeable water ligand. This adaptable precatalyst facilitates diverse transformations such as late-stage C(sp2)–H arylation, alkylation, methylation, hydrogen/deuterium exchange, and more, consistently outperforming traditional ruthenium catalysts. Its broad applicability is highlighted by the potential for rapid photocatalytic reaction screening and the discovery of previously unreported ruthenium reactivities. This suggests a foundational platform for simplifying reactions and accelerating synthetic advancements, expanding the reach of state-of-the-art ruthenium catalysis.
