  Synthesis of stable functionally substituted nitrile oxides of the aromatic series

  摘要：

  Stable functionally substituted mononitrile oxides were obtained from the previously obtained sterically hindered aldehydes of the mesitylene series. The previously unknown bisnitrile oxide was also synthesized from triethylbenzene; the compound is an effective crosslinking agent. The synthesis was carried out via the stage of oximation and oxidation of the oxime by sodium hypochlorite.
