摘要

Treatments of 1-(2, 6-dichlorobenzoyl)-, 3-acetyl-1-(2, 6-dichlorobenzoyl)-, 1-(2, 6- dichlorobenzoyl)-2-formyl-, and 1-(phenylsulfonyl) pyrroles with palladium acetate and alkyl acrylates gave the corresponding α-alkenyl-substituted pyrroles in good yields, while the reaction of 1-(2, 6-dichlorobenzoyl)-2, 5-dimethylpyrrole gave small amounts of β-alkenyl- substituted pyrroles. Under similar conditions, 1-(2, 6-dichlorobenzoyl) pyrazole and 1-(2, ...
