Acetalization of Alkenes Catalyzed by Pd(OAc)2/NPMoV Supported on Activated Carbon under a Dioxygen Atmosphere

Abstract: [reaction: see text] The acetalization of terminal alkenes such as ethyl acrylate and acrylonitrile with alcohols under O2 was efficiently achieved by Pd(OAc)2 supported on activated carbon combined with molybdovanadophosphate (NPMoV). For example, ethyl acrylate was subjected to acetalization with EtOH acidified by CH3SO3H under O2 (1 atm) in the presence of [8 wt%Pd(OAc)2/C] and NPMoV to form ethyl 3,3-diethoxypropionate in quantitative yield.

“…Hosokawa's and Jiang's groups pioneered the reports of Pd(II)‐catalyzed acetalization of acrylates . Then activated carbon‐supported Pd(OAc) 2 acetalization of acrylates was described by Ishii's group . In 2013 Li's group reported the use of the chitosan‐Fe 3 O 4 ‐Pd nanocatalyst for the acetalization of acrylates to synthesize alkyl 3,3‐dialkoxypropionates .…”

“…[21] Das System besteht aus einem [41,42] Ishii et al berichteten unabhängig über ein ähnliches System zur allylischen Oxidation unter Einsatz eines Molybdovanadophosphats (NPMoV) und von Hydrochinon als ETMs (Schema 9); einige ausgewählte Beispiele sind in Tabelle 2 zusammengefasst. [43] Die Reaktivität des Multikatalysatorsystems war von der Ringgröße des Alkens abhängig: Während Cyclopenten und Cyclohexen nahezu quantitativ die entsprechenden Allylacetate lieferten, waren für größere [44] und zur Wacker-Oxidation von Cyclopenten, [45] terminalen Alkenen und Dienen. [46] Dieselben Autoren berichteten über die oxidative Carbomethoxylierung von Alkenen mit dem gleichen Katalysatorsystem (Pd/NPMoV) in einer Kohlenmonoxid/Luft-Atmosphäre und in Methanol als Lösungsmittel.…”
