Trithiafulvenes were prepared through cycloaddition of 3-thioxo-1, 2-dithioles to several electrophilic alkenes and alkynes. Treatments of the product with phenyl-hydrazine and malononitrile afforded the hydrazone and the dinitrilene derivatives respectively. The bromination and subsequent treatment with KCN and malononitrile afforded the diene derivative. The aniline derivative was also obtained by treatment with chloroaniline.
