INTRAMOLECULAR BASE COORDINATION ACCORDING TO NEED - 1-(DIMETHYLAMINOETHYL)-2,3,4,5-TETRAMETHYLCYCLOPENTADIENYL LIGAND IN THE COMPLEXES WITH S-BLOCK, P-BLOCK, D-BLOCK AND F-BLOCK ELEMENTS

The synthesis of cyclopentadienyl complexes containing the polydentate C5Me4(CH2CH2NMe2) ligand is described. The compounds (C5Me4CH2CH2NMe2)2M (M = Ca, Sm), (C5Me4CH2CH2 NMe2)AlEt2, [(C5Me4CH2CH2NMe2)M(CO)2]2 (M = Mo, Fe) and [(C5Me4CH2CH2NMe2)Fe(CO)2]+BF4- are obtained by standard procedures. Except for the dimeric metal carbonyls, all cyclopentadienyl compounds are characterized by an additional intramolecular coordination of the nitrogen atom in the side chain.
