SYNTHESIS OF VARIOUS AROMATIC AMIDE DERIVATIVES USING NITRILE HYDRATASE OF RHODOCOCCUS RHODOCHOROUS J1

Nitrile hydratase, that is produced abundantly in cells of Rhodococcus rhodochorous J1, catalyses the conversion of various aromatic nitrile derivatives to the corresponding amides.Using Rh. rhodochorous J1 resting cells, the conditions for the production of benzamide, 2,6-difluorobenzamide, indolacetamide, thiophenecarboxamide and furanecarboxamide were optimized.Under the determined conditions, 489 g of benzamide, 306 g of 2,6-difluorobenzamide, 1045 g of 3-indoleacetamide, 210 g of 2-thiophenecarboxamide and 522 g of 2-furanecarboxamide were produced, with 100percent molar conversion, from the corresponding nitriles, per litre of reaction mixture.

Synthesis method of insecticide teflubenzuron and intermediate 2,6-difluorobenzamide of insecticide teflubenzuron

The invention discloses a synthesis method of an insecticide teflubenzuron and an intermediate 2,6-difluorobenzamide of the insecticide teflubenzuron, belonging to the field of pesticides. The synthesis method comprises the following steps: step 1, preparation of 2,6-dichlorobenzylidene chloride: preparing turbid liquid of dichlorotoluene and phosphorus pentachloride, introducing chlorine gas, layering materials by utilizing a gas-liquid separator, collecting a crude product, and rectifying the crude product to obtain the 2,6-dichlorobenzylidene chloride; and 2, preparation of 2,6-dichlorobenzonitrile: mixing 2,6-dichlorobenzylidene chloride, acetic acid, zinc chloride, hydroxylamine hydrochloride and sodium acetate, carrying out heating for a reflux reaction, conducting cooling, stirring,filtering and drying successively after the reaction is completed so as to obtain 2, 6-dichlorobenzonitrile. By adopting a one-pot method, a reaction route is shortened, total yield is increased to 67.3% from conventional 55.4%, and cost is greatly reduced.

Ti-superoxide catalyzed oxidative amidation of aldehydes with saccharin as nitrogen source: Synthesis of primary amides

A new heterogeneous catalytic system (Ti-superoxide/saccharin/TBHP) has been developed that efficiently catalyzes oxidative amidation of aldehydes to produce various primary amides. The protocol employs saccharin as amine source and was found to tolerate a wide range of substrates with different functional groups. Moderate to excellent yields, catalyst reusability and operational simplicity are the main highlights. A possible mechanism and the role of the catalyst in oxidative amidation have also been discussed.
