N. Kuhn et al., 1,2-BIS(1',3'-DIMETHYLIMIDAZOLIN-2'-IMINATO)ETHANE - A NOVEL CHELATING LIGAND, Zeitschrift fur Naturforschung. B, A journal of chemical sciences, 53(9), 1998, pp. 997-1003
The reaction of 2-imino-1,3-dimethylimidazoline (10, ImNH) with X-CH2C
H2-X (11, X = p-CH3C6H4SO3) gives the diimine adduct ImN-CH2CH2-NIm .
2 HX (12) from which the diimine ImN-CH2CH2-NIm (13) is obtained on tr
eatment with KH. 13 reacts with (C6H5CN)(2)PdCl2 (15) to give the chel
ate complex (ImN-CH2CH2-NIm)PdCl2 (16). The X-ray structures of 12 and
16 are reported.
