Abstract

Abstract The chlorine functions of CH 3 C (CH 2 Cl) 3, 1, may be replaced by pyrazolyl (pz) as well as imidazolyl (im) residues under the conditions of nucleophilic substitution leading to tripodal ligands CH 3 C (CH 2 X) 3, X= pz, 2; X= im, 3. As a means of introducing two nitrogen donors and one phosphorus donor into a tripod ligand, substitution of the Br and OMs functions in O (CH 2) 2 C (CH 2 Br)(CH 2 OMs), 8, by nitrogen nucleophiles and ...
