Latest Patents
Philippe Leurent's latest patents include a method for the synthesis of exocyclic derivatives of cycloalkyl-hydrazines and exocyclic derivatives of heterocycloalkyl-hydrazines. This invention involves a unique process that demixes a solution containing the synthesized derivative by reacting a heterocyclic amine with monochloramine. The method utilizes an organic phase and an aqueous phase with the addition of anhydrous sodium hydroxide. Notably, the unreacted starting amine can be collected and reused directly, minimizing waste and reducing costs compared to other known methods.
Another significant patent is for the continuous synthesis of monoalkyl-hydrazines with a functionalized alkyl group. This method also features a demixing step, reacting an anhydrous amine with monochloramine, and allows for perfect selectivity in producing monoalkyl-hydrazine without the presence of di- and tri-substituted forms. The unreacted amine is similarly collected and reused, showcasing the efficiency of this innovative approach.
