The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.33100-27-5, Name is 1,4,7,10,13-Pentaoxacyclopentadecane, molecular formula is C10H20O5. In a Article，once mentioned of 33100-27-5, HPLC of Formula: C10H20O5
Starting from tetrakis(trimethylsilyl)stannane, the tris(trimethylsilyl) stannyl alkali derivatives (Me3Si)3SnM, (M = Li, Na, K, Rb, Cs) were prepared in excellent yields. Reaction with MgBr2 ? Et2O afforded bis[tris(trimethylsilyl)stannyl]magnesium. Reaction products were investigated by means of multinuclear NMR spectroscopy. At low temperatures, coupling of 7Li and 119Sn between [(Me 3Si)3Sn]- and [Li ? 3THF]+ (337 Hz) or [Li ? 12Cr4]+ (275 Hz), was observed. NMR chemical shifts and coupling constants of the stannyl anions exhibit a strong dependency on the nature of the cation, solvent system, concentration and temperature. In addition, the molecular structure of tris(trimethylsilyl)stannyl sodium ? 15Cr5 was determined by X-ray crystallography. The [Na ? 15Cr5]+ and [(Me3Si)3Sn]- units are joined by a direct Sn-Na contact, 3.0775(18) A in length.
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.HPLC of Formula: C10H20O5, you can also check out more blogs about33100-27-5
