Deprotonation of the 5-aryl-3-benzyl-1λ4,2-dithiol-1-ylium iodides (6a-6d) obtained by reaction of the 1-aryl-4-phenylbutan-1,3-diones (5a-5d) with hydrogen sulfide and iodine in ethanol gave the stable 5-aryl-3-benzylidene-3H-1,2-dithioles (3a-3d), respectively. The dithioles (3a-3d) underwent thermal cycloaddition reactions with isoselenocyanates and isothiocyanates to give the 2-(substituted amino)-5-aryl-3-phenyl-6,6aλ4-dithia-1-selenapentalenes (7a-7h) andthe 2-(substituted amino)-5-aryl-3-phenyl-1,6,6aλ4-trithiapentalenes (8a-8l), respectively. The dithioles(3a-3d) reacted with isocyanates to give the N-substi-tuted-2-phenyl-2-(5-aryl-3H-1,2-dithiol-3-ylidene) acetamides (11a-11h). © 1997 John Wiley & Sons, Inc.
