摘要

Abstract A highly Lewis acidic aluminum complex was produced using a tridentate ligand 1. The enhanced Lewis acidity of 1-Al was attributed to the combination of a stereoelectronic effect and an electrostatic effect. Comparison with an unstrained complex 4-Al indicated that the ligand-defined sp 3 geometry of the aluminum in 1-Al led to the lower LUMO level and the larger LUMO coefficient on the aluminum. 1-Al promotes a catalytic allylation of ...
