Bases complex with Lewis acid sites while proton transfer to the base occurs at Bronsted acid sites. Each has distinct, well-resolved infrared bands. For example, pyridine forms a complex with the Lewis acid site and produces an infrared absorption band at approximately 1450 cm−1. Pyridinium ...
The reaction was found to be affected by the solvent, temperature and Lewis acid, and the highest de was observed at low temperature and in a polar solvent. The major diastereomer is a result of preferential addition of the dienophile to the si-face of the C=N bond as seen in A. In...

The exact number of Lewis sites is correlated to the preparation technique and not to the framework Si/Al ratio.; The formation of Lewis and Brönsted acid sites in “post-grafted” Al-MCM-41 mesoporous catalysts was investigated step-by-step with 2D HETCOR, a two-dimensional solid-state ...
