azidation method for C–N bond formation at benzylic C–H positions is described using copper-catalyzed visible light photochemistry and the Zhdankin azidoiodinane reagent. The method is applicable to a wide range of substrates bearing different functional groups and having a primary, secondary, or tertiary benzylic position, and is thought to proceed through a radical chain reaction.
The palladium-catalyzed [10% Pd(OH)2/C] reduction of N-(tert-butoxycarbonyl)indoles to the corresponding N-(tert-butoxycarbonyl)indolines is described. Polymethylhydrosiloxane was used as reducing agent and the reaction proceeded smoothly at room temperature in short reaction times giving the products in good yields.
Upon light-induced isomerization, diarylethenes (DAEs) equipped with reactive aldehyde moieties rearrange selectively in the presence of amines, accompanied by decoloration. In a comprehensive study, the probe structure was optimized with regard to its inherent reactivity in the nucleophile-triggered rearrangement reaction. Detailed structure-reactivity relationships could be derived, in particular
