DOI: 10.1039/d2cc04027a
Abstract: Primary and secondary interactions form the basis of substrate activation in Lewis-acid mediated catalysis, with most substrate activations occurring at the secondary binding site. We explore two series of antimony cations, [(NMe2CH2C6H4)(mesityl)Sb]+ (A) and [(NMe2C6H4)(mesityl)Sb]+… read more here.

DOI: 10.3390/molecules30204137
Abstract: This paper reviews methods for partitioning the molecular polarizability into atomic terms. The advantages and disadvantages of hard space or fuzzy partitioning are critically assessed and compared. Polarizability density is proposed as a key function… read more here.
