Chem. Commun., 2026, Accepted Manuscript DOI: 10.1039/D6CC03341E, Communication Jake Tomlinson, Mark J. Muldoon, Paul Dingwall Mechanistic studies of the anti-Markovnikov hydration of terminal alkynes mediated by N,N'-bidentate-ligated ruthenium catalysts are reported. Electronically-asymmetric 2-(2-pyridyl)-benzoxazoles show higher activity compared to standard 2,2'-bipyridyl ligands. Detailed in-situ NMR has...
