Ruthenium-Catalyzed Difluoroalkylation of 8-Aminoquinoline Amides at the C5-Position
A ruthenium-catalyzed highly selective difluoromethylation of 8-aminoquinoline amides at the C5 position has been developed. It tolerates a broad range of functional groups, providing the corresponding difluoromethylated products in moderate to good yields. Preliminary experimental results indicate that the tricoordinate ruthenium intermediate is the key factor in achieving the C5-position selectivity.
Heterocyclic N-acetonylbenzamides and their use as fungicides
Certain N-acetonylbenzamides and their use as fungicides are disclosed. The N-acetonylbenzamides disclosed contain a heterocyclic ring fused to an aromatic ring. These compounds are particularly effective against phytopathogenic fungi of the class Oomycetes. Also disclosed is a method for controlling phytopathogenic fungi by applying one or more of the heterocyclic N-acetonylbenzamides of the present invention, optionally with one or more additional fungicidal compounds.
