Encapsulating ruthenium in silica using a single source precursor: Differing outcomes for a cycloaddition reaction
摘要:
The complex [Ru-2(CO)(4)(mu-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.

integration of non‐native reactivity into metabolic pathways for small‐molecule production has been underexplored. Herein we report a biocompatible iron(III) phthalocyanine catalyst capable of efficient olefin cyclopropanation in the presence of a living microorganism. By interfacing this catalyst with E. coli engineered to produce styrene, we synthesized non‐natural phenyl cyclopropanes directly from D‐glucose
