The tetrachalcogenides [ME 4 (dppe)] (M = Pd, E = S; M = Pt, E = S, Se) react with the activated alkynes RO 2 CC≡CCO 2 R (R = Me, Et) to form the dithiolenes and diselenolenes [M{E 2 C 2 (CO 2 R) 2 }(dppe)]; the structures of the compounds with E = S, R = Et have been determined by X‐ray crystallography; [PdS 4 (dppe)] also reacts with the carbene complex [W(CO) 5 {C(OEt)C≡CPh}] to yield the bimetallic dithiolene [Pd{S 2 C 2 [C(OEt)W(CO) 5 ]Ph}(dppe)].
