WebDec 16, 2005 · A series of new alkoxy-amino-bis (phenols) (H2L 1-6) has been synthesized by Mannich condensations of substituted phenols, formaldehyde, and amino ethers or diamines. The coordination properties of these dianionic ligands towards yttrium, lanthanum, and neodymium have been studied. WebBisphenolate ligands with pyridine and benzene diyl linkers were synthesized and metalated with group 4 and 5 transition metals. The solid state structures of some of the group 4 complexes were solved. The titanium, zirconium, hafnium, and vanadium complexes were tested for propylene, 1 hexene, and ethylene/1 octene polymerization activities ...
