Carbene spacers in bis-porphyrinic scaffolds.
نویسندگان
چکیده
The preparation of two meso-imidazolylporphyrins was achieved in good yield by Ullmann coupling between a meso-bromotriarylporphyrin and imidazoles. Subsequent alkylation afforded the corresponding imidazolium functionalized porphyrins as direct precursors of the carbene. The complexation of these azolium salts with palladium led to trans-anti bis-porphyrin carbenic complexes.

Coordination features of bis(N-heterocyclic carbenes) and bis(oxazolines) with 1,3-alkylidene-2,4,6-trimethylbenzene spacers. Synthesis of the ligands and silver and palladium complexes.
The synthesis of simple imidazolium-based ligand precursors containing a 1,3-alkylidene-2,4,6-trimethylbenzene spacer was examined and different synthetic protocols were applied depending on the nature of the alkylidene arm. For a methylene arm, simple dications 5a,b.2CI were obtained directly. The higher homologue counterparts were conveniently prepared by general multistep routes following a ...
متن کاملSelf-assembly of a bis-porphyrinic supramolecular rectangle using two orthogonal binding strategies.
A bis-porphyrinic rectangle is created via a double self-assembly algorithm using two orthogonal coordination themes, i.e. first a 90 degrees building block composed of a dynamic heteroleptic Cu(I) or Ag(I) bisphenanthroline followed by a coordinative dimerization using the pyridine-zinc porphyrin motif; the spectroscopic and electrochemical properties as well as the dynamic nature of the supra...
متن کاملBridged bis-BODIPYs: their synthesis, structures and properties.
A series of bis-BODIPYs 1-6 bridged via thiophene, furan, N-alkylcarbazole, triphenyl-amine, para- and meta-phenylene groups have been synthesized and characterized by various spectroscopic techniques. The change in the spectroscopic properties of bis-BODIPYs upon varying the size of spacers was studied. X-ray crystal structures of three bis-BODIPYs containing triphenylamine, para- and meta-phe...
متن کاملStable Mixed-Valent Radicals from Platinum(II) Complexes of a Bis(dioxolene) Ligand
Three diplatinum(II) complexes [{PtL}2(μ-thea)] (H4thea = 2,3,6,7-tetrahydroxy-9,10-dimethyl-9,10-dihydro-9,10-ethanoanthracene) have been prepared, with diphosphine or bipyridyl "L" co-ligands. One-electron oxidation of these complexes gave radical cations containing a mixed-valent [thea·](3-) ligand with discrete catecholate and semiquinonate centers separated by quaternary methylene spacers....

Ionic liquid N-ethylpyridinium hydrogen sulfate has been prepared, characterized and used as an efficient recyclable catalyst for the synthesis of a series of indoles and bis(indolyl)methanes. Latter have been further explored for their potential antimicrobial activity against E coli and Bacillus. The ionic liquid used was recycled in the end and its recovery was facilitated b...
