A visible-light photoactivatable di-nuclear PtIV triazolato azido complex?
Chemical Communications Pub Date: 2019-09-02 DOI: 10.1039/C9CC05310G
Abstract
A novel PtIV triazolato azido complex [3]-[N1,N3] has been synthesised via a strain-promoted double-click reaction (SPDC) between a PtIV azido complex (1) and the Sondheimer diyne (2). Photoactivation of [3]-[N1,N3] with visible light (452 nm) in the presence of 5′-guanosine monophosphate (5′-GMP) produced both PtIV and PtII 5′-GMP species; EPR spectroscopy confirmed the production of both azidyl and hydroxyl radicals. Spin-trapping of photogenerated radicals – particularly hydroxyl radicals – was significantly reduced in the presence of 5′-GMP.
