para-Substituted β-ketodithiocinnamic acid dianions react with L MCl [M = Ni, L = PBu ; M = Pd, L = PPh ; M = Pt, L = PEt , PBu , PPh Tol, 1/2 dppe, 1/2 2,9-dimethyl-1,10-phenanthroline (dmphen)] to give the 1,1-ethene dithiolate complexes L M[S C=CH-C(O)-C p-OC ] (3: M = Ni, L = PBu , n = 12; 4a, b: M = Pd, L = PPh , n = 1,8; 5a: M = Pt, L = PEt , n = 1; 5b, 5e-g; 5i: M = Pt, L = PPh , n = 1,8,10,12,14; 5c, h: M = Pt, L = 1/2 dppe, n = 1,12; 5j: M = Pt, L = PPh Tol, n = 12; 6 a-c M = Pt, L = 1/2 dmphen, n = 8, 12, 16); L Pt[S C=CH-C(O)-C -p-C ] (7 a, b: L = PPh , 1/2 dmphen), (Ph P) Pt[S C=CH-C(O)-C -p-C ] (8) and L M[S C=CH-C(O)-C S] (9a: M = Pd, L = PPh ; 9b: M = Pt, L = PEt ; 9c: M = Pt, L = PPh , 9d: M = Pt, L = 1/2 dppe). These compounds have been characterized by their UV, IR, H, C and P NMR spectra.
