Structural characterization of alkyne and vinylidene isomers of [Ru(C2H2)(PMe2Ph)2(Cp)][BF 4]
The reaction of [RuCl(PMe2Ph)2(Cp)] with ethyne and T1BF4 in dichloromethane leads to [Ru(n2-HC?CH)-(PMe2Ph)2(Cp)][BF 4] (2), an unusual n2-alkyne complex of a d6 metal center. This ethyne complex smoothly rearranges to its vinylidene isomer, [Ru(C=CH2)(PMe2Ph)2(Cp)] [BF4] (4), above ca. 60 C in acetone solution. The n2-ethyne to vinylidene conversion can also be carried out by deprotonation of 2 to give [Ru(C?CH2)(PMe2Ph)2(Cp)] (3), followed by protonation of 3 to give exclusively vinylidene isomer 4. Structures of both 2 and 4 were determined by X-ray diffraction. Aside from the difference in the geometry of the C2H2 ligands, the structures are nearly identical. Crystal data with Mo Kalpha (lambda = 0.7107 A) radiation at 297 K are as follows: 2, C23H29BF4P2Ru, a = 23.099 (3) A, b = 9.203 (2) A, c = 11.344 (3) A, orthorhombic space group Pca21 (No. 29), Z = 4, R = 0.054, Rw = 0.074; 4, C23H29BF4P2Ru, a = 23.270 (3) A, c = 9.290 (1) A, c – 11.3659 (8) A, orthorhombic space group Pca21 (No. 29), Z = 4, R = 0.035, Rw = 0.044.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 32993-05-8 is helpful to your research., Reference of 32993-05-8
