Stopped-flow 1,10-phenanthroline

A stopped flow technique coupled with spectrophotometric analysis of the iron (II) complex formed has been used to investigate - the reactions of some organic complexes of iron(III) with the ion Fe ". The iron(III) was complexed with 1,10-phenanthroline, various substituted 1,10-phenanthrolines (5-methyl-, 5-nitro-, 5-chloro-, 5-phenyl-, 5,6-dimethyl-, 4,7-diphenyl-, and 3,4,7,8-tetramethyl-) and 2,2 -dipyridine, 4,4 -dimethyl-2,2 -dipyridine, and 2,2, 2"-tripyridine. The wavelengths used for the analysis lay in the region 500-552 m/i. 

In another recent study, Mao et al. (34k) have used the Cu11 complexes of 2,2 -bypridine and 1,10-phenanthroline to identify the different carbonate coordination modes which may be kinetically significant. Stopped-flow and T-jump techniques were used. The...
