We produce strong evidence of the interaction of ozone with a series of Manganese (III) porphyrinato complexes to form a well defined reactive intermediate. In the latter species, the Manganese atom which is formally in a tetravalent (IV) state, is (

Synthèse d'oxopyranno[g]indoles

Autor: Roger Guilard, Phieo Ta Kim, Panayotis Cocolios

Publikováno v: Canadian Journal of Chemistry. 60:2099-2103

Reaction of ethyl azidoacetate with 6-formyl-4 chromanones, followed by cyclization of the azides obtained leads to 7,8-dihydropyrano[2,3-g]indol-9 (1H)-one. One aspect of the chemical reactivity of these new tricyclic systems is described. The struc

Pentacoordinate iron(III) porphyrin carboxylates: Synthesis, physicochemical characteristics and x-ray crystal structure of acetato(5, 10, 15, 20-tetraparatolylporphyrinato) iron(III)

Carboxylatoiron(III) porphyrins have been synthesised by the action of carboxylic acids on the [(por)Fe]2O dimers. 1H NMR and ESR data of the isolated products are in accordance with pentacoordinate high spin 5/2 ferric complexes, the iron atom being

Synthesis and physicochemical characteristics of alkane (or arene)-thio-, -sulphinato-, and -sulphonato-indium(III) porphyrins. Crystal structure of methanesulphonato(5,10,15,20-tetraphenylporphyrinato)indium(III)

Publikováno v: Journal of the Chemical Society, Dalton Transactions. :2081

Indium(III) porphyrins containing metal–sulphur bonds [InL(SR)](L = porphyrinate, R = alkyl or aryl) are reported. The photochemical oxidation of these leads to the corresponding sulphinatoindium(III) porphyrins [InL(SO2R)]. The insertion of sulphu

Alkane (or arene)-sulphinato and -sulphonato-iron(III) porphyrins: synthesis and physicochemical properties; crystal structure of benzenesulphinato(5,10,15,20-tetraphenylporphyrinato)iron(III)

Publikováno v: Journal of the Chemical Society, Dalton Transactions. :567

Sulphinatoiron(III) porphyrins [FeL(SO2R)](L = porphyrinate, R = alkyl or aryl) have been prepared by the insertion reaction of sulphur dioxide into the Fe–C σ bond of alkyl(or aryl)iron (III) porphyrins [FeLR]. The obtained products are easily ox
