A general strategy for the generation of hypervalent B-centered carboranyl radicals at the B(3), B(4), and B(9) positions was developed for the 1st time via visible-light-promoted I atom abstraction from iodo-o-carboranes by low-valent Ni complex. These radicals react with various (hetero)arenes to afford a wide range of cage B-arylated carborane derivatives at room temperature in very good to excellent yields with a broad substrate scope. Their electrophilicities are dependent on the vertex charges of the cage and follow the order B(3) > B(4) > B(9). Both visible light and Ni catalyst are proved critical to the generation of B-centered carboranyl radicals. The involvement of B radicals is supported by control experiments A reaction mechanism associated with these reactions is also proposed. This strategy offers a new protocol for the generation of B-centered carboranyl radicals at the selected B vertex, leading to a facile synthesis of a large class of cage B substituted carborane mols. This study involved multiple reactions and reactants, such as 2,5-Dimethylthiophene (cas: 638-02-8Related Products of 638-02-8).
2,5-Dimethylthiophene (cas: 638-02-8) belongs to benzothiophene derivatives. Benzothiophene scaffolds are of great importance due to its increased presence in bioactive molecules. Due to its aromaticity, thiophenes do not exhibit the same properties as conventional thioethers.Related Products of 638-02-8
