CONTRIBUTION TO ORGANOLANTHANOIDE CHEMISTRY .3. ON 2-(DIMETHYLAMINOMETHYL)FERROCENYL COMPOUNDS OF SAMARIUM AND YTTRIUM

Earlier results, indicating the ability of the bulky 2-(dimethylaminomethyl)ferrocenyl-group (FcN) to form thermocally stable, heterobimetallic organolanthanide compounds, were proved by the synthesis of organo-rare-earth derivatives (C5Me5)2Sm(FcN) (II), (C5H5)SM(FCN)Cl (III), respectively (C5Me5)Y(FcN)Cl (IV) from the corresponding complex cyclopentadienyl rare-earth chlorides (C5Me5)2SmCl - KCl . THF, (C5H5)SmCl2 . THF and (C5Me5)YCl2 . KCl - 1,8 THF and 2-(dimethylaminomethyl)ferrocenyl lithium (FcN)Li (I) as organylating agent. The synthesized compounds were proved by elementary analysis, IR, H-1, C-13 NMR and UV-VIS spectra as well as by measuring the magnetic moments and by mass spectroscopy.
