Abstract
Abstract The thermal decomposition process of non-natural amino acid tert -butoxycarbonyl- p -fluoro-phenylalanine (FC 6 H 4 CH 2 CH[NHCOOC(CH 3 ) 3 ]COOH, the so-called Boc- p -fluoro-phenylalanine) is slightly different from that of its iodo analogue (IC 6 H 4 CH 2 CH[NHCOOC(CH 3 ) 3 ]COOH, Boc- p -iodo-phenylalanine) The dehydration reaction of the two non-natural amino acids is intramolecular, but not intermolecular. The complex of copper has been prepared through a solid–liquid reaction between the powder of Boc- p -iodo-phenylalanine and the aqueous solution of copper nitrate. The chemical and thermal analysis and the infrared spectra show that the new compound is the complex of p -iodo-phenylalanine and copper with crystal water [Cu(IC 6 H 4 CH 2 CHNH 2 COO) 2 ]·0.5H 2 O. The iodine atom in the organic ligand may also be coordinated directly to the copper ion in crystals of the new complex.
