Amido complexes physical properties

The most relevant E/O co-polymerization reports with rzmzz-Cp-amido titanium complexes include ethylene/1-butene,537,538 ethylene/l-hexene,539,540 and ethylene/l-octene.91,442,454,456,457,464,506,541 Ethylene/4-methyl-l-pen-tene co-polymerizations have been reported as well.457,542 The thermal and physical properties of the octene co-polymers produced with ansa-G -amido titanium complexes have been studied.543-546 The importance of the activator has been pointed out in many instances.91,108... 

TCs are well documented to bind various metal ions, including alkaline earth metals, Al(ni) and transition metals VO(II), Cr(III), Mn(II), Fe(II/III), Co(II), Ni(II), Cu(II) and Zn(II) . TC can form 2 1 TC-metal complexes with transition metal ions in non-aqueous solution, in which the metal is bound at the 2-amido and 3-enolate chelating sites . TCs are present in plasma mainly in the Ca(II)-bound form or Mg(n)-bound form to a lesser extent, when they are not bound to proteins such as serum albumin. Thus, the bioavailability of TCs should be dependent upon the physical and biochemical properties of their metal complexes instead of their metal-free form.
