Preparation method of dichlorotoluene nitride intermediate

The invention belongs to the technical field of preparation of pesticide intermediates, and particularly discloses a preparation method of a dichlorotoluene nitride intermediate. The preparation method comprises the following steps: fully reacting raw materials, a solvent and a nitration reagent to obtain a dichlorotoluene nitride intermediate, wherein the raw materials comprise any one of o-dichlorotoluene, m-dichlorotoluene and p-dichlorotoluene; the solvent is dichloroethane; the nitration reagent is concentrated nitric acid; the dichlorotoluene nitride intermediate is shown as a chemical formula 7 and a chemical formula 12. The preparation method has the advantages that the corrosion to reaction equipment is less, and the generation and discharge of waste acid and waste salt in the production process are greatly reduced.

Model Systems for Flavoenzyme Activity: Relationships between Cofactor Structure, Binding and Redox Properties

A series of flavins were synthesized bearing electron-withdrawing and -donating substituents. The electrochemical properties of these flavins in a nonpolar solvent were determined. The recognition of these flavins by a diamidopyridine (DAP) receptor and the effect this receptor has on flavin redox potential was also quantified. It was found that the DAP-flavin binding affinity and the reduction potentials (E1/2) for both the DAP-bound and unbound flavins correlated well with functions derived from linear free energy relationships (LFERs). These results provide insight and predictive capability for the interplay of electronics and redox state-specific interactions for both abiotic and enzymatic systems.
