Lichtinduzierte orthogonale Bildung kovalenter Bindungen durch zwei Wellenlängen

Abstract: Wirs tellen lichtinduzierte Reaktionen in einem Mehrkomponentensystem vor,d ie durchd ie Wahl der Wellenlänge und des Lçsungsmittels reihenfolgenunabhängig lorthogonal durchgeführt werden kçnnen. 2,5-Diphenyltetrazole werden durch Licht einer LED mit Emissionsmaximum l max = 285 nm mit N-Ethylmaleimid in einer Lçsung aus Acetonitril und Wasser umgesetzt, während gleichzeitig vorliegende o-Methylbenzaldehyd-Thioether nichtr eagieren. Im Gegenzug werden die o-Methylbenzaldhyde durch längerwelliges LED-Licht, l m… Show more

“…[12] The key step is the clean photolysis of tetrazole into an itrile imine dipole. This "photoclick" chemistry has proven to be highly valuable with a variety of alkenes [13,14] and found applicationi nt he light-ligation and labellingo fb iomolecules.
