Infrared Absorption Spectra

An attempt has been made to answer several apparent objections to the structure ethylene-thiuram monosulphide assigned to the monomeric material of formula C4H6N2S3 obtained by air oxidation of disodium ethylenebisdithiocarbamate. Comparison of the ultraviolet and infrared absorption spectra, potentiometric titrations, and biological assays of the compound and several heterocyclic and other compounds containing the N–C–S grouping has eliminated two possible alternative structures containing thiadiazolidine and dithiazolidine ring systems and has led to the conclusion that the original assignment of structure was correct.

Monosubstituted benzoylacetic esters, obtained by condensation of n-alkyl halides with ethyl benzoylacetate, were reacted with hydrazine and phenylhydrazine to give 3-phenyl and 1,3-diphenyl 5-pyrazolones monosubstituted in position 4 by alkyl radicals R (R = H, CnH2n+1(n-1 to 10), and C6H5CH2.). The dissociation constants of the pyrazolones were determined by potentiometric titrations. A study was made of the ultraviolet absorption spectra in both neutral and acid medium and of the infrared absorption spectra. X-ray powder diffraction patterns and data of the pyrazolones were obtained.
