Coordination compounds of ethylenediamine with diaryltin dihalides

Enolisation of acetoacetanilide (AAAH) acetoacet ortho‐toluidide (AATH), 2, 4‐acetoacetxylidide (AAXH), acetoacet‐ortho‐chloroanilide (CAAAH), acetoacetortho‐anisidide (OAAAH), benzoyl‐acetanilide (BAAH) and benzoyl‐meta‐nitro‐acetanilide (NBAAH) have been studied in different solvents of varying polarities, ranging from chloroform (z=63.2) to methanol (Z=83.6) by ultraviolet spectroscopic methods. The low percentages of enol contents in formamide, dimethylformamide and dimethylsulphoxide, may be due to the formation of charge transfer complexes of these solvents with the diketones. Free energy of tautomerisation has also been calculated. The substituents on the phenyl group attached to the nitrogen have no effect on enolisation.

MetaDuring the last few years, studies on the coniplex compounds of benzoyIacetanilide (BAAH) and other P-diketones with metal ions have received major attention from the standpoint of preparation'), chelate formation"'), formation constanta-lo) and magnetic and spectral studies*l). The ability of these compounds to form stable-metal chelates is due to the presence of keto-enol tautornerism e.g. with meta-nitrobenzoylacetacetanilide which results in the formation of six-membered chelate ring.
