Abstract
Summary
A photochemical reduction of CO2 to CO or formic acid was shown using the manganese complexes -missing link parameter-, 100845 or Mn(oMesbpy)(CO)2Br as catalyst in combination with the copper-based photosensitizer [Cu(phen)-(dPPh-Bu)2]2[PF6]2. Turnover numbers (TONs) over 1300 were reached in xx for complex 100845. The highest selectivity for CO (96%) was obtained for catalyst Mn(oMesbpy)(CO)2Br. The experiments were conducted under visible-light irradiation (λ = 436 nm) using BIH as sacrificial reductants (see section SEDs below).
