For dinitrogen activation mediated by a heterobimetallic VFe complex, synthesis and reduction of a novel iron complex having 1,1′-bis(mesitylamido)vanadocene were performed. Reaction of the vanadocene ligand 2 with iron dichloride afforded a heterobimetallic VFe complex 3, characterized by x-ray crystallog. study. The mol. structure of the complex 3 showed the short V-Fe distance of 2.6373(3) Å, indicative of the bonding interaction between two metals. Reduction of the complex 3 with KC8 under a nitrogen atm. was found to result in the formation of a three-coordinate iron dinitrogen complex 4, in which the dinitrogen moiety shows one of the longest N-N bond lengths for iron dinitrogen complexes. Reduction of the complex 3 under an argon atm. was performed to isolate a reduced species [K(thf)5][3] as a reactive intermediate, whose structure was also determined by x-ray crystallog.

1,4,7,10,13-Pentaoxacyclopentadecane(cas: 33100-27-5) is a member of crown ether Ligands. Crown-ethers are macrocyclic polyethers capable of forming host-guest complexes, especially with inorganic and organic cations. Crown-ethers can incorporate protonated primary amine compounds by formation of ion-dipole bonds with the oxygen atoms of the chiral selector. Crown-ethers have been widely used for the separation of several pharmaceuticals both in aqueous and non-aqueous media. Category: ethers-buliding-blocks
