Azo-Hydrazone Tautomerism in Arylazophenoxy Acetic Acids and Their Organotin Complexes
Azo-hydrazone tautomeric equilibria in arylazophenoxyacetic acids and their organotin derivatives have been quantitatively studied.The absence of any marked effect of stannylation of the carboxyl group on the tautomeric equilibrium shows that the N-atom adjacent to the phenoxy ring is involved in N-->Sn coordination in the organotin derivatives, supporting the previously proposed structures for the organotin arylazophenoxy acetates.

Organotin(benzeneazo)phenoxy Acetates - Examples of Seven-coordinated Triorganotin Chelates
Triorganotin derivatives of a number of (benzeneazo) phenoxyacetic acids have been prepared.The derivatives of the tridentate ligands are formulated as six-coordinated organotin complexes on the basis of IR and electronic absorption spectra.Derivatives of
