title: [Synthesis and spectroscopic studies of new N-functionalized macrocyclic compounds and complex].
abstract: Three new N-functionalized tetraazamacrocyclic compounds, C-messo-5,5,7,12,12,14-hexamethyl-1,4,8,11-tetraazacyclotetradecane- N,N',N",N'"-tetrakis (ethyl acetate) (A), C-messo-5,5,7,12,12,14-hexamethyl-1,4,8,11-tetra- azacyclotetradecane-N,N,'N",N'"-tetraacetic acid (H4L) and the hydrobromide of H4L have been synthesized and the complex Na2[NiL].2C2H5OH has been prepared as well. The macroyclic compounds and the complex have been studied by electronic spectrum, infrared spectrum, 1H NMR, MS and elemental analysis.
