The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.14187-32-7, Name is Dibenzo-18-crown-6, molecular formula is C20H24O6. In a Article，once mentioned of 14187-32-7, Computed Properties of C20H24O6
The half-sandwich tetra-tert-butylcarbazol-9-yl iodo complex [(tBu4Carb)Sm(mu-I)(THF)2]2(1) was synthesized by the salt metathesis reaction of tBu4CarbK and SmI2(THF)2in THF. Complex 1 along with metallic Cu was also isolated from the oxidation reaction of (tBu4Carb)2Sm by CuI. The formation of stable radical tBu4Carb.was detected in this non-conventional process, indicating preferential oxidation of anion tBu4Carb?vs. SmII. The treatment of 1 with two equivalents of dibenzo-18-crown-6 resulted in heterolytic dissociation of a eta5-bond Sm-tBu4Carb and afforded an ionic compound [tBu4carb?][SmI(crown)(THF)2]+(4). Alkylation of 1 with o-NMe2C6H4CH2K (1:2 molar ratio) in THF allowed for the synthesis of half-sandwich SmIIalkyl complex (tBu4Carb)SmCH2(o-NMe2C6H4CH2)(THF)2(5) in 55 % yield. The amido complex (tBu4Carb)SmN(SiMe3)2(DME) (6) was obtained by the reaction of 1 with two molar equivalents of NaN(SiMe3)2in THF in 89 % yield.
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.Computed Properties of C20H24O6, you can also check out more blogs about14187-32-7
