Abstract

original image

Kationische Alkylyttrium-Halbsandwichkomplexe katalysieren die ortho-selektive Addition benzylischer C-H-Bindungen von Dialkylpyridinen an eine Reihe von Olefinen wie Ethylen, 1-Hexen, Styrole und 1,3-konjugierte Diene, bei der neue alkylierte und allylierte Pyridine erhalten werden (siehe Schema; Cp=C5Me5). Eine kationische Picolylyttrium-Halbsandwichspezies wie [CpY(2-CH2-6-CH3C5H3N)]+ wurde als entscheidende aktive Spezies bestätigt.
