While the silica-encapsulated ruthenium catalyst and the molecular precursor both catalysed the [2 + 1] cycloaddition reaction between alkenes and ethyl diazoacetate to form cyclopropanes, the intermediate hydrolysis product partially directed the reaction towards [2 + 3] cycloaddition to form cyclic five-membered pyrazolines.||URI:||https://hdl.handle.net/10356/154504||ISSN:||0020-1693||DOI:||10.1016/j.ica.2020.119833||Rights:||© 2020 Elsevier B.V.
