The density of acid sites on amorphous silica alumina has been determined using a combination of gravimetric and spectroscopic analysis using pyridine and 2,4-lutidine and 2,6-lutidine for surfaces treated at different calcination temperatures. An attempt was made to correlate the number of acid sites determined by the different base molecules with the activity for liquid phase reaction of acetone to produce diacetone alcohol at 298 K. The best correlation was obtained with the number of Lewis acid sites which were able to retain pyridine after evacuation at 473 K. The lutidines underestimated the number of Lewis sites on the oxide surface. In particular, 2-6-lutidine was only able to detect Lewis acid sites in geometries at edges and other geometric imperfections on the solid and these were mainly generated after low temperature (573 K) calcination treatment.

The novel, recyclable C2-symmetric chiral shift reagents bearing both squaramide and indanol groups have been synthesized. These squaramides were examined as chiral shift reagents, and they have a wide recognition towards chiral carboxylate anions. The squaramide derived from (1S, 2R)-1-amino-2-indanol can distinguish the absolute configuration of the guest carboxylate anion.

The catalyzed pathway has a lower Ea, but the net change in energy that results from the reaction is not affected by the presence of a catalyst. Formula: C9H11NO, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 126456-43-7, in my other articles.

A density functional theory (DFT) method was used to study the monomer and intermolecular charge-transfer complexes of 22 different alkylpyridines with diiodine. DFT calculations revealed that the sigma* orbital of iodine interacts with the nitrogen lone pair in pyridines. The open-circuit photovoltage (Voc) values of a bis(tetrabutylammonium)cis- bis(thiocyanato)bis(2,2?-bipyridine-4-carboxylic acid, 4?-carboxylate)ruthenium(II) (N719) dye-sensitized nanocrystalline TiO2 solar cell with an I-/I3- redox electrolyte in acetonitrile using alkylpyridines additive were compared to computational calculations on the interaction between pyridines and I 2 by a DFT method. The optimized geometries, frequency analyses, Mulliken population analyses, and interaction energies suggest that the V oc value of the solar cell is higher, the more alkylpyridine complexes with I2.

The kinetics of the forward and reverse steps of the process [Pt(NNN)Cl]+ + am ? [Pt(NNN) (am)]2+ + Cl- (NNN = 2,2?: 6?,2?-terpyridine ; am = one of a number of pyridines and NH3 covering a wide range of basicity) have been studied in methanol at 25C. Both forward and reverse reactions obey the usual two-term rate law observed in square-planar substitution. The reactivity and the ability of the chloro-complex to discriminate among the nucleophiles, as well as the sensitivity of the rate of the chloro entry upon the nature of the displaced base and the steric factors in both the forward and reverse processes are discussed in terms of intimate mechanism and compared with data for a number of different PtII systems. The equilibrium constants for the reactions have been determined from the ratio of the rate constants.

Reaction of [IrCp?Cl2]2 with ferrocenylimines (Fc=NAr, Ar=Ph, p-MeOC6H4) results in ferrocene C-H activation and the diastereoselective synthesis of half-sandwich iridacycles of relative configuration Sp?,RIr?. Extension to (S)-2-ferrocenyl-4-(1-methylethyl)oxazoline gave highly diastereoselective control over the new elements of planar chirality and metal-based pseudo-tetrahedral chirality, to give both neutral and cationic half-sandwich iridacycles of absolute configuration Sc,Sp,RIr. Substitution reactions proceed with retention of configuration, with the planar chirality controlling the metal-centred chirality through an iron-iridium interaction in the coordinatively unsaturated cationic intermediate.
