H-bond donor catalysts able to modulate the reactivity of ionic substrates for asym. reactions have gained great attention in the past years, leading to the development of cooperative multidentate H-bonding supramol. structures. However, there is still a lack of understanding of the forces driving the ion recognition and catalytic performance of these systems. Herein, insight into the cooperativity nature, anion binding strength, and folding mechanism of a model chiral triazole catalyst is presented. Our combined exptl. and computational study revealed that multi-interaction catalysts exhibiting weak binding energies (≈3-4 kcal mol-1) can effectively recognize ionic substrates and induce chirality, while strong dependencies on the temperature and solvent were quantified. These results are key for the future design of catalysts with optimal anion binding strength and catalytic activity in target reactions. This study involved multiple reactions and reactants, such as Tetramethylammonium chloride (cas: 75-57-0Formula: C4H12ClN).
Tetramethylammonium chloride (cas: 75-57-0) belongs to organic chlorides. Organic chlorides can cause corrosion in pipelines, valves and condensers, and cause catalyst poisoning. The hydrocarbon processing industry (HPI) and others are affected by damage caused by these substances. Organochlorine compounds are lipophylic, meaning they are more soluble in fat than in water. This gives them a high tenancy to accumulate in the food chain (biomagnification).Formula: C4H12ClN
