Abstract

Summary: The reaction of L2TiCl2 (1)(L= v5-C5H4-SiMed with 1 equiv of LiC= CC= CC& (2) yields Lz-Ti (C= CC= CC&XCl)(3). 3 reacts with 2 to afford L2Ti (C= CC= CC2H& (4a); 4a also can be prepared by treatment of 1 with 2 equiv of 2. The compounds L2Ti-(C= CC= CC2Hd (Cl)(3) and L2Ti (CWC= CR) 2 (4a, R= C2H5; 4b, R= SiMed can be used as organometallic chelating ligands for the stabilization of monomeric
