The sensitive balance between five-coordinate carbene and six-coordinate carbyne ruthenium complexes formed from ruthenium vinylidene precursors

The reaction of the dichloro(vinylidene)ruthenium compounds [RuCl2(=C=CHR)L2] (R = Ph or tBu and L = PCy3 or PiPr3) (1a-d) with [H(OEt2)2]BArf (BArf- = [B{C6H3 (CF3)23,5}4]-) resulted in the attack of the proton at the Cβ carbon atom of the vinylidene ligand and afforded the corresponding cationic, five-coordinate carbyneruthenium complexes [RuCl2(≡CCH2R)L2]BArf (2a-d) in almost quantitative yields. The protonation of the carboxylato derivatives [RuCl(κ2-O2CR)(=C=CHPh) (PiPr3)2] [R = H (3a), CH3 (3b), or Ph (3f)] with [H(OEt2)2]BArf led to the formation of the five-coordinate cyclic carbene complexes [RuCl{=C(CH2Ph)OC(O)R}(PiPr3)2]BArf [R = H (6a), CH3 (6b), or Ph (6f)], which are formed via nucleophilic attack of the carboxylato ligand to a cationic carbyneruthenium intermediate. The protonation of the related vinylidene compounds [RuCl(κ2- O2CR)(=C=CHPh)(PiPr3)2] [R = CH2F (3c), CHF2 (3d), CF3 (3e), C6H4NO2-4 (3g), C6H4NO2-2 (3h), C6F5 (3i), and C6H3(NO2)2-2,4 (3j)] with [H(OEt2)2]BArf gave an equilibrium mixture of the carbyne [RuCl-(κ2-O2CR)(≡CCH2 Ph)(PiPr3)2]BArf (5c-e, 5g-j) and the isomeric, cyclic carbene complexes [RuCl{=C(CH2Ph)OC(O)R} (PiPr3)2]BArf (6c-e, 6g-j). The position of this equilibrium significantly depends on the basicity of the carboxylato ligand. The six-coordinate cyclic carbene complexes [Ru(κ2-O2CR1){=C(CH2Ph)OC(O) R2} (PiPr3)2]BArf [R1 = R2 = CHF2 (7a), CF3 (7b); R1 = CF3, R2 = H (7c)] were obtained on protonation of the precursors [Ru(κ1-O2CR1) (κ2-O2CR2)(=C=CHPh) (PiPr3)2] (4a-c) with [H(OEt2)2]BArf. Both 7a and 7b undergo a fluxional process in solution resulting in a κ1/κ2 interconversion of the carboxylato groups. The crystal and molecular structures of 2b, 5e, and 6a were determined by X-ray crystallography.
