At room temperature, o-carboryne efficiently undergoes ene reaction with a variety of alkynes and alkenes possessing an aCH proton, yielding a series of o-carboranyl allenes and alkenes in good yields. This reaction has a broad substrate scope and provides a facile synthetic method for obtaining cage C-substituted carboranyl allenes and alkenes, which can be utilized as useful starting materials for synthesizing multifunctionalized carboranes.
o-Carboryne undergoes at room temperature an efficient ene reaction with a large variety of alkynes and alkenes possessing an aCH proton to give a series of o-carboranyl allenes and alkenes in good to high isolated yields. This reaction has a broad substrate scope from alkyl and aryl to silyl substituents. This protocol provides a facile synthetic method for accessing cage C-substituted carboranyl allenes and alkenes, which may be utilized as useful starting materials to synthesize multifunctionalized carboranes.
