Abstract: A ti ta nium imido com plex, ButN=TiClPy2[2-Me2NCH2-(C4H3N)] 1, was syn the sized through me tath e sis
by re act ing ButN=TiCl2Py3 with lith ium 2-(dimethylaminomethyl) pyrrolate (LLi) in di ethyl ether at room tem -
per a ture. The dark brown red crys tals were ob tained from a con cen trated di ethyl ether so lu tion of com pound 1
at -20 C and the monoclinic crys tal shows a dis torted oc ta he dral struc ture with two py ri dines tak ing trans po si -
tions. Hy dro ly sis ButN=TiCl2Py3 with 2,2’-methylene-bis(6-t-butyl-4-methylphenol) (HO~~CH2~~OH) gen -
er ates a bis phenoxide ti ta nium com plex, (O~~CH2~~O)TiCl2Py 2, by elim i nat ing one equiv a lent of ButNH2.
Sim i larly, the re ac tion of LH with PhN=WCl4(OEt2) in di ethyl ether at room tem per a ture gen er ates
PhN=WCl3(L) 3, in mod er ate yield. 3 has been char ac ter ized by NMR spectroscopies and X-ray crys tal log ra -
