Synthesis and metallochromic properties of some new mono- and bishydrazones of benzil and 2,2'-pyridil.
Preparation of some new mono- and bishydrazones which possess the ferroin chromophoric group is described, together with results of spectrophotometric studies of their chelation reactions with iron(II), copper(I), cobalt(II), nickel(II) and zinc(II). Several of the new compounds show promise as chromogenic reagents for these metals. The results are also of interest with regard to structure-reaction relationships.
