Oliver Fabian Geis has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Metal-catalyzed arylations of hydrazines, hydrazones, and related substrates
    Publication number: 20010031894
    Abstract: A method is provided for the transition metal-catalyzed arylation, or vinylation, of hydrazines, hydrazones, and the like. Additionally, the invention provides a conceptually novel strategy, the cornerstone of which is the transition metal-catalyzed arylation or vinylation method, for the synthesis of indoles, carbazoles, and the like. The methods and strategies of the invention may be utilized in standard, parallel, and combinatorial synthetic protocols.
