Se-Alkynyl selenocarboxylates (1) were found to readily react with alcohols and amines to give O-alkyl selenocarboxylates (4) and selenoamides (6) in moderate to good yields, respectively. The formation mechanisms of 4 and 6 via selenoketene and ammonium alkyneselenolate, respectively, are proposed.
