Regioselektive Pd‐katalysierte Methoxycarbonylierung von Alkenen unter Verwendung von Paraformaldehyd/Methanol als CO‐Surrogat

Abstract: In den letzten Jahren wurde intensiv an der Entwicklung neuartiger carbonylierender Transformationen mit CO-Alternativen geforscht, die es ermçglichen, das toxische CO-Gas durchb esser handhabbare anorganische oder organischeC arbonylverbindungen zu ersetzen. Hier wird über die erste regioselektive Methoxycarbonylierung von Alkenen mit Paraformaldehyd und Methanol als CO-Ersatz berichtet. Dieses neue Verfahren ist für eine Reihe von Alkenen in Gegenwart von Palladium-Katalysatoren unter relativ milden Bedingun… Show more

“…Considerable efforts have been focused on the development of CO surrogates for carbonylation reactions . The typical known CO surrogate compounds include methanol, 1,3‐dioxolane, formaldehyde, paraformaldehyde, silacarboxylic acids, formic acid and its derivatives, acyl chloride derivatives, carbon dioxide, metal carbonyls, and N ‐formylsaccharin (NFS) . These reagents offer CO in situ upon heating or metal catalysis or treatment with acid or base to avoid handling the gas; some of them even can be recycled after release of CO. For instance, NFS, working as an easily accessible and highly reactive crystalline CO surrogate, can be easily synthesized from saccharin and also can be reused …”
