Electric Literature of 52409-22-0, Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 52409-22-0, Pd2(DBA)3, introducing its new discovery.
Palladium-Catalyzed Annulation of Phenazastannines with 9-(Dibromomethylene)fluorene and -(thio)xanthenes: Facile Synthesis of Acridine Moiety-Containing Bis(tricyclic) Aromatic Enes
Growing interest has been paid to bis(tricyclic) aromatic enes as key components of functional organic materials such as molecular switches and charge-transporting materials. Currently, the synthetic approaches to the overcrowded alkenes are limited to McMurry coupling and Barton-Kellog olefination. This communication reports that palladium-catalyzed double cross-coupling reaction of phenazastannines with 9-(dibromomethylene)fluorene, -xanthene, -thioxanthene, and -thioxanthene-S,S-dioxide serves as a facile synthetic approach to bis(tricyclic) aromatic enes such as 9-(9H-fluoren-9-ylidene)acridines, 9-(9H-oxanthen-9-ylidene)acridines, 9-(9H-thioxanthen-9-ylidene)acridines, and 9-(10,10-dioxido-9H-thioxanthen-9-ylidene)acridines.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.Electric Literature of 52409-22-0. In my other articles, you can also check out more blogs about 52409-22-0
