Iron-Catalyzed Cycloaddition of Alkynenitriles and Alkynes
摘要:
The combination of Fe(OAc)(2) and an electron-donating, sterically hindered pyridyl bisimine ligand catalyzes the cycloaddition of alkynenitriles and alkynes. A variety of substituted pyridines were obtained in good yields.

Nucleophilic addition of an organorhodium(I) to a cyano group has been observed for the first time in the rhodium-catalysed reaction of cyano-substituted alkynes with arylboronic acids. The higher reactivity of a cyano group relative to an alkoxycarbonyl group toward an organorhodium(I) species is demonstrated by an intramolecular example.
