Summary

Traduction automatique

Detaljerede og generaliserede protokoller præsenteres for syntesen og efterfølgende oprensning af fire palladium- N- heterocykliske carbenkomplekser fra benzimidazoliumsalte. Komplekserne blev testet for katalytisk aktivitet i arylation og Suzuki-Miyaura reaktioner. For hver undersøgt reaktion katalyserede mindst et af de fire komplekser reaktionen succesfuldt.
