′-aryl or Alkenylpiperazines: A Copper-Catalyzed C-N Cross-Coupling in the Presence of Aryl and Alkenyl Triflates and DABCO
introduction of an aryl and alkyl motif onto the piperazine is not always straightforward, direct arylation and alkenylation of 1,4‐diaza‐bicyclo[2.2.2]octane would obviate the inefficiencies associated with the preparation of these target molecules. We have utilized alkyl halides, aryl or alkenyl triflates, and 1,4‐diaza‐bicyclo[2.2.2]octane for the synthesis of N‐alkyl‐N′‐aryl or alkenylpiperazines
The present invention relates to novel antiviral compounds which are covalently attached to solid, macro surfaces. In another embodiment, the invention relates to novel antiviral compositions including a polymeric material and, embedded therein, an antiviral compound. In other embodiments, the invention relates to making a surface antiviral and making a polymeric material antiviral.

enhanced flexibility and resistance to bending and stretching. Using these designed ILs, two mixtures were developed and crafted to facilitate the effective curing of epoxy resin, which was examined using Differential Scanning Calorimetry (DSC). Investigation of the resin crosslinking process revealed that the mixtures of ILs exhibited a lower total enthalpy of thermal conversion than single-IL systems. Moreover
