Nitriles react with sodium hydrogen selenide, pyridine and hydrochloric acid in ethanol to give primary aryl and alkyl selenocarboxamides. The alkyl selenocarboxamides are converted into selenazoles by reaction with phenacyl bromide.
The reaction of nitriles with P 2 Se 5 in the presence of EtOH/H 2 O afforded a variety of primary selenocarboxylic amides.
在 EtOH/H 2 O 存在下,腈与 P 2 Se 5 的反应提供了多种伯硒羧酸酰胺。
