Abstract
Reactions of ruthenium silylene complexes of the type [Cp*(PMe3)2RuSiR2]+ with unsaturated compounds were investigated. Nonpolar, unsaturated substrates such as ethylene, acetylene, and 2-butyne do not react with [Cp*(PMe3)2RuSiR2]B(C6F5)4 (1a, R = Me; 1b, R = Ph). However, methyl isocyanate inserts into an Si−S bond of the silylene complex [Cp*(PMe3)2RuSi(STol)2][BPh4] (5) to give the 1,2-dipolar addition product {Cp*(PMe3)2RuSi(STol)[η2−O(MeN)C(STol)]}[BPh4] (6a) in 87% yield. This product was characterized by X-ray crystallography as possessing a base-stabilized silylene ligand with thiolate and thiocarbamate substituents. Compound 1a reacts with methyl and phenyl isocyanate to give the 2 + 2 R = Me; 8, R = Ph). The analogous triflate R = Ph; 10, R = Me) were prepared by reaction of the appropriate ruthenium silyls Cp*(PMe3)2RuSiR2OTf with methyl isocyanate. Heating 9 to 100 °C in toluene resulted in dissociation of the isocyanate and regeneration of the triflate Cp*(PMe3)2RuSiPh2OTf. Competition react...
