- ItemControlled keto-enol tautomerism of coumarin containing beta-ketodithioester by its encapsulation in cucurbit[7]uril(2017) Aliaga Miranda, Margarita Elly; García-Río, Luis; Numi, Ambar; Rodríguez, Alejandra; Arancibia-Opazo, Sandra; Fierro Huerta, Angélica; Cañete Molina, Álvaro
- ItemCucurbit[7]uril as a Supramolecular Catalyst in Base-Catalyzed Reactions. Experimental and Theoretical Studies on Carbonate and Thiocarbonate Hydrolysis Reactions(2021) Fierro, Angelica; Garcia-Rio, Luis; Arancibia-Opazo, Sandra; Alcazar, Jackson J.; Santos, Jose G.; Aliaga, Margarita E.Cucurbit[7]uril (CB7) catalyzes the hydrolysis reaction of bis(4-nitrophenyl)carbonate (1) but inhibits that of bis(4-nitrophenyl)thiocarbonate (2). Two relevant CB7 effects are proposed, a base-catalyst mediated by the CB7 portal and an inhibitory role attributed to the lower interaction of the thiocarbonyl group with the solvent in the host cavity, respectively.
