Conclusions 1.The reaction ofa-alkoxyacroleins with semi-, thiosemi-, and selenosemicarbazides in a basic medium leads to the formation of semi-, thiosemi-, and selenosemicarbazones ofa-alkoxyacrolein. The reactions of a-ethoxyacroleins with twofold excess amounts of semi- and selenosemicarbazides in acid media lead to disemi- and diselenosemicarbazones of methylglyoxal.2.Determination of basicity constants of semicarbazide and its S-, Se-, and NH-analogs was carried out in acetonitrile. |
