This report describes the synthesis of organoselenyl isoquinolinium imides through a tandem cyclization between N′-(2-alkynylbenzylidene)hydrazides and diselenides. The reaction was carried out at room temperature under an ambient atmosphere using cheap iron(III) chloride as the metallic source. The strategy shows good tolerance to a broad range of N′-(2-alkynylbenzylidene)hydrazides and diselenides
