Abstract:In the current study, new carbazole‐based formazan dyes, D‐A and D‐π‐A, were synthesized, and their spectroscopic properties were studied for the first time. For this aim, carbazole aldehyde compounds were modified by the derivatization of carbazole, a natural electron‐donor compound, from 3‐ and 9‐position. Then, hydrazone derivatives were synthesized from these aldehyde derivatives. Finally, D‐A (5A–C) and D‐π‐A (6A–C) carbazole–formazan dyes were obtained by the interaction of the hydrazone compounds with p… Show more

The directing group-assisted regioselective C–H activation of carbazoles and indolines is achieved via transition metal-catalyzed reactions. This C–H functionalization protocol provides rapid access to install diversely functionalized succinimide groups at...
This is the first systematic review of the most relevant approaches to direct C(sp2)–H bond functionalization of azomethine derivatives. The scope of the applicability of various transformations is analyzed. The review assesses prospects of the application of this functionalization strategy in the multistep synthesis of valuable compounds for use in medicinal chemistry, materials science and related areas.
