Chemical Processes in Systems CuI(CuII)/L/[B12H12]2–/solv (L = bipy, phen; solv = CH3CN, DMF, and CH2I2)

Аннотация

Processes proceeding in the Cu^I(Cu^II)/L/(L = bipy, phen) systems in the presence of the [B₁₂H₁₂]^2– anion, which has the lowest reduction ability among the boron cluster anions [B_nH_n]^2– (n = 6, 10, 12), have been studied. It has been found that the preparation of Cu^I and heterovalent Cu^I/Cu^II complexes with azaheterocyclic ligands and the [B₁₂H₁₂]^2–anion requires the Cu^II reduction process to be initiated. To minimize the redox process in the Cu^I/L/[B₁₂H₁₂]^2– system, redox-active starting components have been added to the reaction system. Mono- and polynuclear copper complexes with various composition and structures have been isolated as a result of redox reactions proceeding in the Cu^I(Cu^II)/L/[B₁₂H₁₂]^2–/solv (L = bipy, phen; solv = CH₃CN, DMF, CH₂I₂) systems.
