Rhodium-Catalyzed Stitching Reactions for the Facile Synthesis of Extended π-Conjugated Compounds

Abstract

π-Conjugated compounds have been extensively investigated as potentially useful organic materials, however, accessible structures are currently still limited, mainly due to the lack of efficient synthetic methods. In this regard, a new synthetic strategy termed the ‘stitching reaction’ has been recently devised that allows facile access to novel types of bridged π-conjugated compounds in a convergent manner under rhodium catalysis. In addition, this synthetic strategy has been successfully applied to the preparation of π-conjugated polymers that cannot be synthesized via existing methods. Herein an overview that includes the physical properties of newly synthesized π-conjugated compounds is provided.
