Wasserstoffübertragungen, 8. Heterogen‐katalysierte Wasserstoff‐Transfer‐Reaktionen an Metalloxiden

Abstract: Fur den H-Transfer bei Dihydroarenen in kondensierter Phase erweist sich vor allem Chrom(II1)-oxid als guter Katalysator. Die Wasserstoffabstraktion verlauft als getrennter erster Schritt in einem mehrstuligen, ionischen Mechanismus, trotzdem (miiioig) regio-und stereoselektiv. Danach erfolgt cis-Addition an ein Akzeptormolekiil. Die Reaktion ist von Isomerisierungen (bei Olefinen und Alkinen) und einem H/D-Wquilibrieren begleitet.

“…Such reactions include double bond hydrogenation (in batch this reaction needs 250 °C and 40–50 bar for yield of 64%) and chemoselective reduction of ketones (in batch: required 0 °C to yield of 76%). 4 6 Furthermore, using deuterated water, deuterated products can also be synthesized (in batch: Wilkinson catalyst with 20% yield). 5 Examples are listed below with their reaction conditions.…”

“…4 6 Furthermore, using deuterated water, deuterated products can also be synthesized (in batch: Wilkinson catalyst with 20% yield). 5 Examples are listed below with their reaction conditions. As can be seen in table 1, using the H-Cube makes it easy to reach high conversion and purity.…”
