AROMATIC ISOTHIOCYANATES REACTIONS WITH E PSILON-AMINO-CAPRONIC ACID ETHYLIC AND GLYCOLIC ESTER

New thiourea derivatives were synthesized, starting from the following aromatic isothioscyanates; phenyl isothiocyanate, o-, m-, p- tolyl is othiocyanate, p- bromine and p- iodine phenyl isothiocyanate, with the epsilon- amino-caprionic ethylic ester and glycolic ester, respective ly. The compounds were characterized by elementary analysis and IR spe ctroscopy and their structure was thus confirmed. The reactions took p lace in a completely anhydrous medium the yields being in excess of 85 %, function of the reagents structure. The compounds obtained served a s standard in characterizing the sulphur containing polymers got from the epsilon- amino-caprionic acid glycolic ester, with the aromatic di isothiocyanates.
