Electric Literature of 2926-30-9, A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 2926-30-9, Name is Sodium trifluoromethanesulfonate, molecular formula is CF3NaO3S. In a Article,once mentioned of 2926-30-9
The synthesis of the bifunctional iminophosphorane-NHC (1) based on the imidazo[1,5-a]pyridin-3-ylidene (IPy) platform is reported. Its imidazo[1,5-a]pyridinium salt precursor [1·H](X) was readily obtained by an efficient three-component coupling reaction between 5-bromoimidazo[1,5-a]pyridinium bromide, sodium azide, and triphenylphosphine according to a SNAr/Staudinger reaction sequence. The stable free carbene 1 was generated by deprotonation of [1·H](X) with potassium bis(trimethylsilyl)amide, and its coordination ability toward various transition-metals was evaluated, either upon direct metalation of the free carbene or by transmetalation from a silver(I) NHC complex. While the ligand 1 is singly bounded through the carbene carbon atom in the latter complex, it behaves as a chelating bidentate ligand in all other complexes that were prepared, including the cationic and neutral palladium(II) complexes [Pd(allyl)(kappa2C,N -1)](OTf) ([5](OTf)) and [PdCl2(kappa2C,N -1)] (7), and the cationic rhodium(I) complexes [Rh(cod)(kappa2C,N -1)](OTf) ([8](OTf)) and [Rh(CO)2(kappa2C,N -1)](OTf) ([9](OTf)), generating stable 5-membered metallacycles. IR muCO measurements carried out on the complex [Rh(CO)2(kappa2C,N -1)](OTf) ([9](OTf)) show evidence of the strong donating character of the iminophosphorane-NHC ligand 1.
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.Electric Literature of 2926-30-9, you can also check out more blogs about2926-30-9
