Abstract

in favor of the “diphenyl-hydroxy-biuret” structure, Kjellin found that P-ethyl-(or P-methyl-) hydroxylamine reacted in ether solution with but one molecular equivalent of phenyl isocyanate to produce a compound of the formula CGHBNH-CO-N (OH)-C~ HB, which gave an intense color reaction with ferric chloride. Although the structure of this is unquestioned, it should not be necessary to go into detail to explain that this com-
