    Description / Table of Contents: 1,2-Dithia-cyclopentenes, X VI 1). I,2-Dithia-cyclopenten-3-ones and Grignard CompoundsGrignard compounds react at the disulfide bond of 4,5-benzo-1,2-dithia-cyclopentenone (1) and of 5-amino-1,2-dithia-cyclopentenones 10. Chemical and physical methods are used to confirm the structures of the reaction products.
