Description

Reaction of [MnIII(acac)3] and [VIVO(acac)2] with the 1,4-diazabutadiene (DAB) ligands Ph-DAB-(CH2)3R [R = Si(OEt)3(1a); H (1b)] (L) leads to complexes of the type [MnII(acac)2L] and [VIVO(acac)L]Cl in good yields. These complexes were characterised by spectroscopic techniques, and magnetic measurements showed that in the case of the manganese the metal was reduced during the reaction with the nitrogen ligand. http://www.sciencedirect.com/science/article/B6TH4-4PNFVD0-2/1/fc74a9a65915d80c7e1ed24c826f6af6
