Abstract
This invention relates to novel isonitriles, including arylthio isonitriles, and methods for their preparation. The isonitriles include a conjugated ring system. The structure is designed with the flexibility to have multiple substitution patterns. The isonitriles may be used in applications including, but not limited to, pharmaceutical compositions.
