Phenylazoalkenes 4 with full substitution at the terminal carbon atom react with thiocyanic acid affording 2,3,5,6,7,7a-hexahydro-3-phenyl-1H-imidazo[1,5-b][1,2,4]triazole-2,5-dithiones 8. The bicyclic compounds 8 result from two consecutive [3+2] cycloaddition steps, thus adding a novel facet to the classical "Criss-cross" reaction.
