WebThe mechanism of the activation of hydrocarbons as apolar molecules in the absence of oxygen is of particular interest. The biochemistry of anaerobic toluene degradation has been studied in detail. Toluene is activated by addition to fumarate to yield benzylsuccinate, which is then further metabolized via benzoyl-CoA. Webbetween ET and HAT mechanisms in the oxidations of alkylbenzenes. To check this conclusion a study of TSP selectivity in the oxidation of alkylbenzenes promoted by metalloporphyrins and by microsomal cvtochrome P-450 has been carried out, which has allowed us to assign a HAT mechanism to these riactions, in full accord with previous …
