Six-coordinate cobalt(III) tetraphenylporphyrins, XCoIIITPP(Py) (Py = pyridine and X = N3, Cl, and SCN), exhibit dual photoreactions: the photoejection of axial pyridine and the photochemical homolysis of the X-Co bond. The former is

The cycloaddition of nitriles and of dimethylacetylenedicarboxylate to the azide ligand of polymeric Schiff Base cobalt(III) and phosphine palladium(II) complexes gives the corresponding tetrazolate and triazolate complexes from which the heterocycles could be cleaved by hydrogen chloride.Usually the yields are low; if the heterocycle is soluble in ether or sublimable, yields up to 30percent have been obtained.Using this method the hitherto unknown 5-trichlormethyltetrazole could be prepared which was characterized by an X-ray structural analysis.Similarly, the cycloadditi on of azido(tetraphenylporphinato)cobalt(III) with nitriles, cyclohexylisocyanide and MeO2CCCCO2Me affords the corresponding complexes with heterocyclic ligands.The preparation of tetraphenylporphyrinato(tricyanmethanido)cobalt(III), (TPP)CoN=CC(CN)2, is reported. - Key words: Tetrazoles, Triazoles, Polymeric Schiff Base Cobalt(III) Complexes, Phosphine Palladium Complexes with Azide, Tetrazolate and Triazolate Ligands
