Conclusions

  1. 1.

    The reaction ofα-alkoxyacroleins with semi-, thiosemi-, and selenosemicarbazides in a basic medium leads to the formation of semi-, thiosemi-, and selenosemicarbazones ofα-alkoxyacrolein. The reactions of α-ethoxyacroleins with twofold excess amounts of semi- and selenosemicarbazides in acid media lead to disemi- and diselenosemicarbazones of methylglyoxal.

     
  2. 2.

    Determination of basicity constants of semicarbazide and its S-, Se-, and NH-analogs was carried out in acetonitrile.
