The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.12150-46-8, Name is 1,1-Bis(diphenylphosphino)ferrocene, molecular formula is C34H28FeP2. In a Article£¬once mentioned of 12150-46-8, Formula: C34H28FeP2
New Mono-Dinitrogen Complexes of Molybdenum That Produce Ammonia and Hydrazine
A new, extensive series of mono-N2 complexes of molybdenum is reported.The sodium amalgam reduction of MoCl3(triphos), where triphos=PhP(CH2CH2PPh2)2, in tetrahydrofuran solution in the presence of 2L or L2 and with a deficiency of N2 led to the formation of Mo(N2)(triphos)(L2) (1A-F): 1A, L2=2 PPhMe2; 1B, L2=Me2PCH2PMe2; 1C, L2=1,2-(Me2As)2C6H4; 1D, L=Ph2PCH2PPh2; 1E, L2=Ph2PCH2CH2PPh2; 1F, L2=1,1′-(Ph2PC5H4)2Fe, DPPFe.Complexes 1C and 1E were each a mixture of isomeric mono-N2 complexes.Complex 1F was isolated together with Mo(triphos)(eta2-DPPFe)(eta1-DPPFe).Complexes 1A-F all reacted with HBr in CH2Cl2 to afford ammonia, hydrazine, and N2 (and some H2) in varying yields.The highest yield of ammonia was obtained from 1F, and the highest yield of hydrazine was obtained from 1A (HCl/toluene at 70 deg C).
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.Formula: C34H28FeP2, you can also check out more blogs about12150-46-8
