Synthesis, structure and electrochemistry of CO incorporated diruthenium metallacyclic compounds [Ru2(CO)6{μ-η1:η1:η2:η2-1,4-Fc2C5H2O}] and [Ru2(CO)6{μ-η1:η1:η2:η2-1,5-Fc2C5H2O}]
摘要:
Ferrocenyl substituted ruthenium metallacyclic compounds, [Ru-2(CO)(6){mu-eta(1) :eta(1)eta(2):eta(2)-1,4-Fc(2)C(5)H(2)O}] (1) and [Ru-2(CO)(6)-{mu-eta(1):eta(1):eta(2):eta(2)-1,5-Fc(2) C5H2O}] (2) have been synthesized and structurally characterized. Electrochemical studies for 1 and 2 and the respective quinone derivatives 3 and 4 show weak to no electrochemical coupling at the mixed-valent intermediate state which is dependent on the complex frameworks.
