Abstract

Reaction of Metal Cyclopentadienides with 3,5-Bis(methylthio)-1,2dithiolium Salts.-Thallium or lithium cyclopentadienes react with 1,2dithiolium salts via S,S-bond cleavage to give rise to intramolecular Diels-Alder adducts. Furthermore, the intramolecular condensation product (XIII) or the product (XII) resulting from substitution of a methylthio group can be formed. -(HARTKE, K.; POPP, X.-P.; Heterocycles 40 (1995) 1, 85-88; Inst.
