The complexes of 1-(5-tetrazolylazo)-2-naphthol with some metal ions

Kinetics and mechanism of chelation of nickel(II) by a tridentate .alpha.-[(2-hydroxyphenyl)azo]-.alpha.-acetoacetonitrile and an .alpha.-(8-quinolylazo)-.alpha.-acetoacetonitrile dye

“…The results are interpreted in terms of the generally accepted multistep sequence for chelation (eq [6][7][8][9] where L-L-L represents the tridentate dye. Under conditions where the steady-state approximation applies to the unidentate and bidentate intermediates 5 and 6 the second-order rate constant for formation of MD is given by eq 10, which was derived by assuming that fc_3 is negligible.…”
