Abstract

Two different strategies were used to synthesize tri (2-alkoxy-5-nitrophenyl) methanes 6a, b. The X-ray structures of 6a and its precursor 5 show the molecules in a conformation with a syn-orientation of the nitro and alkoxy groups. Hydrogenation and acylation by the appropriate active ester gave the corresponding tri-CMPO derivatives 4a, b. Their ability to complex lanthanide ions was studied by NMR spectroscopy and by nuclear magnetic ...
