The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.14098-44-3, Name is Benzo-15-crown-5, molecular formula is C14H20O5. In a Article£¬once mentioned of 14098-44-3, Application In Synthesis of Benzo-15-crown-5
Synthesis of cyclohexadienyl ruthenium arene complexes by replacement of acetonitrile ligands in [(eta5-C6H7)Ru(MeCN) 3+
Heating of the cyclohexadienyl ruthenium complex [(eta5-C 6H7)Ru(MeCN)3+ (1) with arenes results in replacement of acetonitrile ligands giving complexes [(eta5-C6H7)Ru(arene)+ (arene = toluene, o-xylene, hexamethylbenzene, p-toluidine, benzo-15-crown-5, ethyl ester of N-acetylphenylalanine) in 53-93% yields. Similar reaction of 1 with naphthalene produces labile complex [(eta5-C6H 7)Ru(naphthalene)+ which readily undergoes solvolysis in acetone. The reaction of 1 with 1,5-cyclooctadiene unexpectedly gives the benzene complex [(eta3,eta2-C8H 11)Ru(C6H6)+ in 44% yield, as a result of formal abstraction of two hydrogen atoms. Energy decomposition analysis revealed that the cyclohexadienyl ruthenium cation [(eta5- C6H7)Ru+ is less arenophilic then [CpRu + due to weaker orbital interaction with arenes. The structure of [(eta5-C6H7)Ru(benzo-15-crown-5)PF 6 was established by X-ray diffraction.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Application In Synthesis of Benzo-15-crown-5, you can also check out more blogs about14098-44-3
