A regio- and stereoselective synthesis of new vinyl selenocyanates (yields 76–93 %), containing N-alkylamide groups and heterocyclic amide substituents, has been developed based on the reaction of 3-trimethylsilyl-2-propynamides with potassium selenocyanate. The reaction proceeds in the presence of ammonium chloride in aqueous acetonitrile and is accompanied by a desilylation process.
M. V. Andreev (Wed,) studied this question.
