| Abstract: | L-histidine substitutes cyano groups of K4Fe (CN)6 at pH 7·0 on irradiation with ultraviolet light. The reaction follows first order kinetics with reference to K4Fe(CN)6 and zero order with reference to histidine. The kinetic data shows the primary process to be aquation of Fe(CN) 6 4? while the final product is formed through a rapid dark reaction of histidine with Fe(CN)4 (H2O) 2 2? to give the product K2Fe(CN)2(histidine)2. The final product has been subjected to chemical and infrared spectral analysis. |
