摘要

Cationic dialkylaluminum and m-terphenylalkylaluminum compounds catalyze the intramolecular hydroamination of primary and secondary aminopentenes. The reaction rates are strongly dependent on the substrate and the catalyst substituents. The bulky species [Dipp∗ AlEt][CHB11H5I6](Dipp∗= 2, 6-Dipp2C6H3–, Dipp= 2, 6-iPr2C6H3–), 4, was the most active catalyst. Although the neutral species DcpAlEt2 (Dcp= 2, 6-(2, 6-Cl2C6H3) ...
