Thermodynamics and kinetics of reaction of (Oxo)(hydroxo)molybdenumtetraphenylporphyrin with pyridine

The reaction of meso-tetraphenylporphyrin with Mo(VI) oxide in boiling phenol resulted in a stable complex O=Mo(OH)TPP. Thermodynamics and kinetics of the reaction between (oxo)(hydroxo)molybdenumtetraphenyporphyrin with pyridine in toluene were studied by spectrophotometric method. This reaction was found to occur in three equilibrium elementary stages: replacement of OH- by Py (K 1=9.1 × 103 l/mol, k 1=5.25 s-1 mol-1 l), the formation of dication (dipyridine)(hydroxo)molybdenumtetraphenylporphyrin as a result of cleavage of a double bond Mo=O (K 2=39.3 l/mol, k 2=1.83 × 10-2 s-1 mol-1 l), and the formation of cationic complex[Mo(Py)3TPP]3+ ? 3OH- (K 3=1.0 l/mol, k 3=1.19 × 10-3 s -1 mol-1 l).

Chemical composition of donor–acceptor complexes of hydroxyoxo(5,10,15,20-tetraphenylporphinato)molybdenum(V) with 3,5-dimethylpyrazole and equilibrium constants for their formation

The results from a quantitative study of reactions between hydroxyoxo(5,10,15,20-tetraphenylporphinato)molybdenum(V) (O=Mo(OH)TPP) and 3,5-dimethylpyrazole, a biologically active base, in toluene are presented. The chemical structure and key parameters of intermediates and reaction products are determined by spectral means. The equilibrium constant (K = 51.3 L/mol) is calculated and a full kinetic description of simple reactions that occur in this system during complex transformation is obtained. The prospect of using a mixed porphyrin-containing complex as a receptor for 3,5-dimethylpyrazole, a building block for alkaloids and pharmaceutical preparations, is substantiated.

Synthesis and properties of a novel porphyrin–fullerene triad assembled through donor–acceptor bonding

Complexation of (hydroxy)(oxo)(5,10,15,20-tetraphenylporphyrinato) molybdenum(v) with 2’,5’-di(2-pyridyl)-1’- (3-pyridylmethyl) pyrrolidino[70]fullerene leading to a new donor–acceptor triad is characterized by quantitative description of the equilibrium and the reaction rate. The prospects of the triad as a photosynthetic antenna imitator and an active layer in solar energy conversion devices are substantiated.

Synthesis and Structural Characterization of the Metalloporphyrin Dimer, 2, the First Product from the Reaction of Mo(CO)6 with H2TPP (tetraphenylporphyrin)

Ligand substitution equilibrium in the macrocyclic molybdenum(V) complex

The thermodynamics of the reaction of tetraphenylporphyrin(oxo)(hydroxo) molybdenum with imidazole (Im) in toluene was studied spectrophotometrically in a polythermal mode. It was established that the reaction of Im with O=Mo(OH)TPP includes several stages, two of which can be studied by spectrophotometrical titration. The first equilibrium stage is Im coordination to the eighth coordination site (K 1 = 1.85 × 103 l/mol), the second stage is the coordination of the second Im molecule with the displacement of OH- into the outer sphere (K 2 = 4.80 × 10 2 l/mol). The enthalpy and entropy contributions to the stability constant of tetrapheny lporphyrin molybdenum(V) complexes with Im were determined. Nauka/Interperiodica 2007.

Ligand substitution reactions in (dichloro)hafnium(IV) tetraphenylporphine and (oxo)(hydroxo)molybdenum(V) tetraphenylporphine

Extra coordination and substitutions in the first coordination sphere of mixed-ligand metal porphyrins (Cl)2HfTPP and O=Mo(OH)TPP (TPP stands for the meso-tetraphenylporhine) with a molecular ligand H2S and an anionic ligand HSO4- (ligands with weak affinities to metal cations in metal porphyrins) is studied. The substitution of a hydrosulfate ion for the O2- and OH- anionic ligands in the molybdenum complex is irreversible when in concentrated aqueous H 2SO4, monohydrate, or HOAc + H2SO4 mixtures. The reaction with H2S, which is reversible in toluene, is studied by spectrophotometric titration. The stepwise substitution constants for (Cl)2HfTPP (K1 = 82 l/mol, K2 = 289 l/mol) and the one-stage SH--for-OH- substitution constant for O=Mo(OH)TPP (Ke = 83 l/mol) are determined. Both complexes are candidates for use as activators of gas-separating membranes and as components of H2S-selective sensors.
