| Abstract: | Tetraazacyclodecane-N, N', N", N'-tetramethylenephosphonic acid (DOTP) and 1,4,8,11-tebraazacyclotetradecane-N, N', N",N'-tetramethylenephosphonic acid (TETP) were respectively synthesized by Mannich-type reactions of 1, 4,7,10-tetraazacyclododecane and 1, 4, 8, 11-tetraazacyclotetradecanewith phosphorous acid and formaldehyde in thepresence of concentrated hydrochloric acid. The PH dependence of the chemical shifts of the peaks exhibitedby these macrocyclic aminophosphonic acids was studied. And then,La3+ and Gd3+ complexes with DOTP orTETP were prepared with an improved synthetic technique of macrocyclic compounds. |
