✦ Synopsis

Palladium(0)-Catalyzed Allylation of Highly Acidic and Non-Nucleophilic Arenesulfonamides, Sulfamide, and Cyanamide. Part 2. Formation of Medium and Large Heterocycles.

-Reactions of the title substrates, carried out in the preceding paper with monoallylic carbonates, are now investigated with allylic bis-carbonates (I) and (II). Medium-and large-ring unsaturated heterocycles instead of the expected three-and/or five-membered products are obtained. The yields are generally very low; in most cases complex mixtures containing additionally oligomers and/or Pd-bound systems are formed.
