C(sp3)–H bond activation by the carboxylate-adduct of osmium tetroxide (OsO4)

The carboxylate adducts of OsO4 ([OsO4(X)], X = AcO and BzO) were isolated and their structures, physicochemical properties and reactivity were explored. The C(sp3)−H oxygenation mechanism by the carboxylate adducts was discussed based on their kinetics and DFT studies.

About this collection

2021 is a huge milestone for Dalton Transactions – the publication of its 50th volume! Since its launch in 1972—then named Journal of the Chemical Society, Dalton Transactions—the journal has published over 45,000 articles featuring contributions from over 100 countries across six continents. Dalton Transactions is a truly international journal with an international readership and this global reach is a result of the work of our many editorial and advisory board members over the years.

This themed collection celebrates the high quality research published in Dalton Transactions authored by our board members past and present. The breadth and diversity of the field of inorganic chemistry is illustrated by this collection, as well as the new avenues being explored.

Further articles will be added to the collection as they become available. I hope you enjoy reading these articles and here’s to another 50 years of Dalton Transactions!
