Formation of supramolecular complex between imidazole and dichloro(5,10,15,20-tetraphenylporphinato)zirconium(IV)

By the reaction of 5,10,15,20-tetraphenyl-21H,23H-porphin (H 2TPP) with zirconium tetrachloride in boiling benzonitrile a complex was obtained, dichloro(5,10,15,20-tetraphenylporphinato)zirconium(IV), (Cl) 2ZrTPP. The equilibrium and reaction rate of stepwise reactions of (Cl)2ZrTPP with imidazole (Im) in toluene were investigated by spectrophotometry. It was established that the three steps of the complex formation include reversible processes of coordination of Im molecule and substitution of 2Cl-by the second and third Im molecules. The products of the first and second stages of the reaction, (Cl)2(Im)ZrTPP and [(Cl)(Im)2ZrTPP]+Cl-, respectively, are unstable and dissociate slowly at one Zr-Cl bond. By the analysis of the numerical values of the reactions parameters with accounting for the existence of definite spectral response to the presence of an organic base was shown a better prospect of application of (Cl)2ZrTPP in sensor systems than those of metallophtalocyianines and doubly charged cation complexes with porphyrins.

Reaction of (POR) M(OAc)2 (M = Zr, Hf) with nBuLi and solid state structure of [(TPP)Zr(μ-OH)2]2

A general route to (TPP)Zr(OAc)2, (OEP)Zr(OAc)2 and (TPP)Hf(OAc)2 from the reaction of MCl4 and H2(POR) in benzonitrile, followed by treatment with pyridine + acetic acid is described. The reaction of (POR)M(OAc)2 with nBuLi occurs in a stepwise manner, with approximately 2 equiv. of nBuLi required before the formation of M(nBu) is observed, and 4 equiv. required for stoichiometric conversion to (POR)M(nBu)2. The tetrahydroxo-bridged dimer [(TPP)Zr(μ-OH)2]2 was obtained as the benzene solvate from the hydrolysis of (TPP)Zr(nBu)2, and the structure was determined by single crystal X-ray diffraction (triclinic, P1; a = 10.606(2) A, b = 13.003(3) A, c = 14.587(3) A, α = 99.85(3)°, β = 107.61(3)°, γ = 96.82(3)°, Z = 2).
