Ruthenium complexes / Sulfur dioxide complexes / Sulfene complexes / Nucleophilic addition 679 Sulfur(1V) Compounds as Ligands. 19 ['I. -Cationic Ruthenium-Sulfene Complexes: Synthesis and Reactions. Crystal Structure Analysis of [Cp*(Me3P)zRu(CHz = S02)]PF6 Methylene addition to coordinated sulfur dioxide yields the dohalides, amines, including ..nonnucleophiles" such as ethylnovel $( C,S) sulfene complexes [Cp(dppm)Ru(CHR = SOz)]PF6 diisopropylamine and DBU, and phosphanes to 3. The regio-(R = H 3, Me: 4) and [Cp*(Me3P),Ru(CHz = SO2)]PF6 ( ). An Xselectivity of the reaction of 3 with enamines is opposite to ray structure determination of 5 reveals a relatively short C -S that of free sulfene, i.e. coordination of the sulfene to ruthebond (167.5 pm). The sulfene complexes are powerful carbon nium effects umpolung. electrophiles as shown by the rapid addition of halides, pseu-
