Intramolecular Hydroamination of Aminoalkynes with Silver−Phenanthroline Catalysts
摘要:
Intramolecular hydroamination of several aminoalkynes catalyzed by silver-phenanthroline complexes is reported. This catalyst system complements previous protocols by employing air- and moisture-stable complexes without compromising activity or reaction control. Some of the hydroamination products are subject to a useful aerobic oxidation. Silver-phenanthroline complexes have successfully demonstrated efficacy in the desymmetrization of a prochiral diyne.

The ZnâZn bonded compound [(η5-Cp*)2Zn2] was investigated as catalyst for the inter- and intramolecular hydroamination reaction. High reaction rates under mild conditions were observed. This is the first application of a ZnâZn bonded compound as catalyst.
