Synthesis and structural characterization of eta6-arene ruthenium complexes bearing pentadienyl and oxopentadienyl ligands
General methodology for the synthesis of cationic ruthenium(II) eta5-pentadienyl compounds stabilized by the (eta6- C6Me6)Ru fragment has been developed. Pentadienyl compounds [(eta6-C6Me6)Ru{eta5- CH2C-(R2)CHC(R4)CH(R5)}]BF 4 (R2 = R4 = R5 = H, 2-BF 4; R2, R4 = H, R5 = Me, 3; R 2, R4 = Me, R5 = H, 4) can be prepared in good yields from reactions of the labile dication [(eta6-C 6Me6)Ru(acetone)3](BF4)2 (1) with 1-trimethylsilyl-2,4-pentadiene, 1-trimethylsilyl-2,4-hexadiene, and 2,4-dimethyl-1-trimethylstannyl-2,4-pentadiene, respectively. Compound 3 is isolated in 90% yield as a mixture of the syn and anti isomers. In contrast, the reaction of pentadienyllithium with [(eta6-C6Me 6)RuCl2]2 provides a nonselective reaction, which affords a mixture of isomeric eta1- eta3-, and eta5-coordinated pentadienyl complexes, [(eta6-C 6Me6)Ru(eta5-CH2CHCHCHCH 2)]Cl (2-Cl), [(eta6-C6Me6) Ru(eta3-CH2CHCHCH=CH2)-Cl] (5), and [(eta6-C6Me6)Ru(eta1-CH 2CH=CHCH=CH2)Cl]2 (6); the reaction of 1,4-pentadiene and [(eta6-C6Me6)RuCl 2]2 in ethanolic carbonate similarly gives a mixture containing complex 5, [(eta6-C6Me6) Ru{eta3-C(Me)CHC(Me))Cl] (7), and [(eta6-C 6Me6)Ru(eta3-CH2CHCHCH 2Me)Cl] (8). Using a similar strategy for the synthesis of the corresponding oxopentadienyl derivatives is much more complicated, even when using an enol silane as the nucleophilic precursor, reflecting a greater competition among alternative bonding modes for the oxopentadienyl derivatives compared to the corresponding pentadienyl analogues. The reaction of lithium oxopentadienide and [(eta6-C6Me6)RuCl 2]2 in THF affords [(eta6-C 6Me6)Ru(eta3-exo-syn-CH2C(Me) CHC(Me)O)Cl] (11) in poor yield, although this complex readily affords [(eta-C6Me6)-Ru(eta5-CH2C(Me) CHC(Me)O)]BF4 (9) upon reaction with silver tetrafluoroborate. The analogous eta6-benzene complex, [(eta6-C 6H6)Ru(eta3-exo-syn-CH2C(Me) CHC(Me)O)Cl] (13), can be prepared, albeit in very low yield, in an analogous manner to that reported for complex 11, along with traces of an isomeric congener, 13-endo. The use of 1-trimethylsilyloxy-1,3-butadiene unexpectedly provided strongly contrasting results upon addition to dicationic complex 1, returning a mixture of eta5- and eta3-oxopentadienyl complexes [(eta6-C6Me6)Ru(eta5- CH2CHCHCHO)]BF4 (14) and [(eta6-C 6Me6)Ru(1-3,5-eta-exo-syn-CH2CHCHCHO)] 2-(BF4)2 (15). Addition of water to the dimeric product 15 affords the monomelic aquo adduct [(eta6-C 6-Me6)Ru(eta3-exo-syn-CH2CHCHCHO) (H2O)]BF4 (16), but this complex is unstable toward isolation, reverting back to dimer 15 upon precipitation. A more stable adduct, [(eta6-C6Me6)Ru(eta3-exo-syn- CH2-CHCHCHO)(MeCN)]BF4 (17), is isolated upon dissolution in acetonitrile, and addition of aqueous NaCl to 15 gives compound [(eta6-C6Me6)Ru(eta3-exo-syn- CH2CHCHCHO)Cl] (20). Compound 14 affords the decarbonylation product [(eta6-C6Me6)Ru(eta3-allyl)(CO)] BF4 (19) as a mixture of exo and endo allyl isomers. The solid-state structures for compounds 2-BF4, 4, 9, 11, 13, 15, and 19-exo, as determined by X-ray crystallography, are also reported.
The reactant in an enzyme-catalyzed reaction is called a substrate. Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction.I hope my blog about 37366-09-9 is helpful to your research., COA of Formula: C12H12Cl4Ru2
