Allylation of N-Heterocycles with Allylic Alcohols Employing Self-Assembling Palladium Phosphane Catalysts
摘要:
The first palladium catalyst system that allows the direct allylation of indoles with allylic alcohols as substrates with water being the only byproduct is presented. The application of self-assembing ligands based on complementary hydrogen bonding was the key to success.

Novel bis(acetylacetonato)ruthenium(II) complexes bearing the 6-diphenylphosphino-N-pivaloyl-2-aminopyridine and 3-diphenylphosphinoisoquinolone ligands were synthesized. Molecular structures of these complexes were studied in solution and also in the solid state, and unusual hydrogen-bonding patterns were identified. The prepared compounds constitute active catalysts for the hydration of nitriles
