Abstract

Reaction of a variety of monoprotonic selenoamide derivatives with 1, 2-bielectrophiles such as a-bromophenylacetyl chloride and 2-bromo-2-ethoxycarbonylacetyl chloride gave representatives of the anhydro-4-hydroxy-l, 3-selenazolium hydroxide mesoionic ring system possessing varying degrees of stability. These reacted with dimethyl acetylenedicarboxylate giving the corresponding pyridones with extrusion of selenium ...
