Photoreduction and deprotonation of [Co(1,3,6,8,10,13,16,19-octa-aza-bicyclo[6.6.6]icosane)][BPh4]3 in organic media
Abstract
Irradiation with visible light of [Co(sep)][BPh4]3, (sep = 1,3,6,8,10,13,16,19-octa-azabicyc[6.6.6]icosane) in aprotic solvents gave a divalent cobalt complex [Co(sep)][BPh4]2, air-oxidation of which produced a complex containing a trivalent cobalt atom and a deprotonated sep ligand.
