“…The oxidation of hydrocarbon catalyzed by metalloporphyrins has been known for several decades [117] , and aerobic oxidation of hydrocarbon by polyhalogenated metalloporphyrins has also been reported [44]. However, the catalytic activity of the metalloporphyrins was generally poor, the catalyst life was short, and catalysts were extremely expensive.…”

“…One is a high-value metal-oxo species mechanism, one is metal-bound alkylperoxide mechanism, and the last is a radical-chain autoxidation mechanism. Lyons [44,102] and Therien [ 107] have found that an iron (IV)-oxo porphyrin complex (PFe IV =O, Cpd II) generated by μ-oxo iron porphyrin thermal disproportionation (Scheme 18, marked by blue line), is involved in polyhalogenated ironporphyrins oxidation of isobutane through the UV-vis and high pressure NMR measurements. Haber et al [109] proposed that homolytic cleavage of alkyl peroxide manganese(III)porphyrin complexes PMn III OOR result in ketone as the main reaction product in the study of manganeseporphyrin-catalyzed oxidation of cyclooctane.…”

“…In order to search after more evidence of the mechanism in Lyons catalyst system, Lyons [44,[102][103], Labinger [68,[104][105], Therien [106][107], and Harber [108][109] have made many ground-breaking work. There are three main reaction mechanisms in Lyons catalytic system.…”

“…Adipic acid is a valuable raw material used in the production of fibers, lubricants, plasticizers, and food additives as well as in the production of intermediates for pharmaceuticals, insecticides, and bactericides. Conventionally, it is manufactured by oxidation of cyclohexanone / cyclohexanol, by hydrogenation of phenol, or more commonly, by oxidation of cyclohexane (Davis et al, 1991;Castellan et al, 1991).…”

Síntese de materiais poliméricos contendo moléculas bioativas e materiais de fontes renováveis via catálise enzimática Dissertação apresentada ao Instituto deO objetivo deste trabalho é sintetizar materiais provenientes de fonte de matéria prima renovável e de fácil degradação, através de sínteses enzimáticas, evitando assim o uso de catalisadores metálicos tóxicos. Além disso, pretendeu-se agregar moléculas biologicamente ativas, de forma que os produtos finais possam exibir propriedades farmacológicas. As substâncias bioativas selecionadas para este trabalho foram: pantenol, ácido azeláico, ácido cítrico, e pantolactona.Destas moléculas, foram sintetizados 8 materiais poliméricos: poli(azelato de pantenila), poli(adipato de pantenila), poli(adipato de isosorbila-co-pantenila), poli(azelato de isosorbila), poli(adipato-co-azelato de isosorbila), poli(citrato de isosorbila), poli(adipato de isosorbila-co-citrato) e oligômero de polipantolactona.Todos os materiais foram sintetizados utilizando a enzima Candida antarctica fração B (CAL-B) como catalisador, em solvente orgânico, utilizando peneira molecular para remoção do subproduto da reação. As caracterizações foram feitas através de RMN-1 H, MALDI-ToF e GPC. Since the invention of the first synthetic polymer by John Wesley in 1868, the use of this class of materials has continuously grown. Currently, there is a great interest in adding nobler attributes to these materials, such as their use in biological devices, quality of rapid degradation and, more recently, the preference for those made from renewable feedstock, reducing the environmental impact generated by the use oil and derivatives. PalavrasThe objective of this work is to create materials of renewable material origin and easy degradation, using enzymatic catalysis thus avoiding the use of toxic metal catalysts. Furthermore, we intended to add biologically active molecules, so that the final products may exhibit pharmacological properties. The bioactive substances selected for this study were: panthenol, azelaic acid, citric acid, and pantolactone.From these molecules eight different polymeric materials were synthesized:poly(pantenyl azelate), poly(pantenyl adipate), poly(isosorbyl-co-pantenyl adipate), poly(isosorbyl azelate), poly(isosorbyl adipate-co-azelate) poly(isosorbyl citrate), poly(isosorbyl adipate-co-citrate) and oligomer of polypantolactone. All materials were synthesized using the enzyme Candida antarctica fraction B (CAL-B) as catalyst in organic solvent using molecular sieves to remove the byproduct of the reaction. The characterizations were made by 1H NMR, MALDI-ToF and SEC.Keywords: Panthenol, azelaic acid, citric acid, ascorbic acid, pantolactone, glycerol, isosorbide, CAL-B drug delivery. A busca por materiais biodegradáveis pode também provir de matéria derivada de fontes renováveis, como a biomassa, excelente na substituição do combustível fóssil devido a sua disponibilidade inesgotável e diminuição do impacto ambiental devido ao "sequestro de carbono".
