Abstract

original image

Auf direktem Weg zum Aldehyd: Hydrosilylierungen mit einem NHC-Eisen-Komplex unter UV-Bestrahlung ermöglichten die selektive Reduktion von Estern zu Aldehyden (siehe Schema; NHC= N-heterocyclisches Carben). Die niedrige Katalysatorbeladung und sehr milden Reaktionsbedingungen machen diese chemoselektive Transformation zu einer vielversprechenden Alternative für die Ester-Reduktion mit Diisobutylaluminiumhydrid.
