Both n → π* and anion–π interactions seem to be similar in nature, but the origin of these two attractive interactions is very much different. The anion–π interaction originates mostly from electrostatics (anion-quadrupole) … Ver más Further, Reedijk and co-workers have designed two triazine-based compounds which self assemble to form structures stabilized by both C–H⋯π and lp⋯π interactions.79 The … Ver más Raines and co-workers have argued that N-acyl homoserine lactones, similarly to the proline residue, can exhibit an n → π* interaction between the proximal carbonyl groups.44 They were able to crystallize N-trimethyl homoserine … Ver más Web23 de jul. de 2024 · Although individual n→π* interactions are relatively weak (∼0.3–0.7 kcal/mol), the ubiquity of carbonyl groups across chemistry and biology gives the n→π* …
