 Title    Synthesis of Cationic Ruthenium Thioketene Complexes through Intramolecular 1,2-Elimination [1]  
 Abstract    Halfsandwich thiocarboxylate complexes [CpRu(PR3)->(SC(0)CH2R')] ((P R 3)2 = (PPh3)2, Ph2PCH 2PPh2 (dppm), Ph2PC2H4PPh2 (dppe); R' = C6H 5, 4-C6H4Me, 4-C6H 4OMe, 4-C6H4C1) are obtained from the corresponding thiolate complexes [CpRu(PR3)2SH] and acyl chlorides. The structure of [CpRu(dppm)(SC(0)CHTPh)] was determined: monoclinic space group P2j/c (No. 14), a = 9.229(2), b = 16.680(3),"c = 21.447(5)Ä, ß = 90.751(12)°, Z = 4. Reaction of the thiocarboxylate complexes with the anhydrides of either trifluoro-acetic acid or trifluoromethanesulfonic acid gives thioketene complexes [CpRu(dppm) (?;2-S=C=CHR')]PF(s. H ie structure of [CpRu(dppm)0/2-S= C = C H Ph)]PF6 was deter­ mined: monoclinic space group P2,/c (No. 14), a -13.814(5), b -15.338(2), c = 17.057(7) Ä, ß = 93.74(2)°, Z = 4.
