This fact is all the more interesting when it is remembered that ethylic orthonitrophenylpropiolate behaves so differently when treated in the same way. Baeyer (Bey., 14, 174) , who studied this reaction, has shown that on treating the ortho-derivative with sulphuric acid, a simple intramolecular change takes place, ethylic iaatogenate being formed :-0 2 E thy lic orthon itroyhenylpropiolate. Ethylic isatogenate.
