Oxidative carbonylation of hydroxyaromatic compounds

Organolead compounds such as tetraethyllead are useful in catalyst compositions for the oxidative carbonylation of hydroxyaromatic compounds to diaryl carbonates. They are employed in combination with a Group 8, 9, or 10 metal such as palladium, or a compound thereof, and a bromide or chloride such...

Zusammenfassung:	Organolead compounds such as tetraethyllead are useful in catalyst compositions for the oxidative carbonylation of hydroxyaromatic compounds to diaryl carbonates. They are employed in combination with a Group 8, 9, or 10 metal such as palladium, or a compound thereof, and a bromide or chloride such as tetraethylammonium bromide.
