Abstract
The structure of the fluorescent compound (A) obtained from the reaction of dulcin and sodium nitrite was previously presumed to be 1, 3-bis (4-ethoxyphenyl)-5-tetrazolone. In this paper, (2-bromoethoxy) phenyl derivative (B) which has the same structural skeleton of compound A was synthesized and analized by the single crystal X-ray diffraction method to determine the structure more conclusively. The structure of compound B was discussed on the basis of the result of the two-dimensional analysis. The structure of the fluorescent compound A was consequently concluded as 1, 3-bis (4-ethoxyphenyl)-5-tetrazolone.
