Abstract The complex [Ru2(CO)4(µ-O2CCH2OSi(OEt)3)2(PPh3)2] was used as a single-source precursor to prepare silica-encapsulated ruthenium via hydrolysis followed by calcination. 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.
