AbstractCarborane is a cluster composed of carbon, boron and hydrogen atoms. It has been received a great attention for its applications in organometallic/coordination chemistry, [1] drug design[2] and versatile materials.[3] In this connection, a variety of methodologies have been developed for the synthesis of functionalized carboranes. Recently, our group reported a nickel-catalyzed arylation of carboranes with the assistance of Grignard agents.[4] In this presentation, we described an efficient strategy for the synthesis of aryl-o-carboranes and o-carborane-fused cyclics through light-induced Ccage-Csp2 coupling. This work represents a clean, efficient, transition-metal-free and cheap synthesis of functionalized carboranes, which has significant advantages over the known methods.[5]
This work was supported by a grant from the Research Grants Council of HKSAR.
