Abstract

original image

Geschützte Katalyse: Neuartige Kern-Schale-Nanokatalysatoren bestehend aus einem aktiven Palladium-Nanopartikel als Kern und einer Schale aus Sulfoxid-Makroliganden wurden hergestellt. Die Schale schützt den Katalysator vor einer Koordination durch Alkene und ermöglicht die Blei-freie selektive Semihydrierung eines breiten Spektrums von Alkinen ohne jegliche Additive (siehe Schema).
