摘要:
The reaction of titanium tetrachloride in toluene at - 78 degrees C with S equivalents of N,N',N''-trimethylethylenediamine yields a monomeric titanium tetrachloride adduct, [TiCl4(Me(2)NCH(2)CH(2)NMeH)] (1). The complex [TiCl2(Me(2)NCH(2)CH(2)NMeH)(2)] (2) is prepared by the reaction of titanium tetrachloride with 4 equivalents of N,N',N''-trimethylethylenediamine at - 78 degrees C. The X-ray crystal structure of 1 reveals that it has a distorted octahedral structure, with the chelating amine ligand in a delta-gauche conformation.
