The multi-gram synthesis of a wide range of 1,2,3-triazolines via azide–alkene cycloaddition reactions in a Deep Eutectic Solvent (DES) is reported. The role of DES in this transformation as well as the origin of the full product distribution was studied with an experimental/computational-DFT approach.

attractive approach to investigate and control GPCR dimerization may be provided by the exploration and characterization of bivalentligands, which can act as molecular probes simultaneously binding two adjacent binding sites of a dimer. The synthesis of bivalent dopamine D2 receptor ligands of type 1 is presented, incorporating the privileged structure of 1,4-disubstituted aromatic piperidines/piperazines

Many azobenzene-based applications rely on variations in the 'head' group of the chromophores. We present a method to chemically modify azobenzenes quickly and easily, and report the effects that these modifications have on the properties of the azobenzene chromophores. Using now common 'click' chemistry, we have developed a methodology which can be applied in a one-pot fashion to rapidly vary the molecular structure, permitting the synthesis of libraries of dyes while allowing for the retention of photophysical characteristics. We validate this synthetic approach as not changing the nature of the chromophores in our testing of 17 derivatives, indicating that this is a good strategy for easy and rapid molecular tailoring. The results of this study will facilitate the use of these versatile molecules in material science, as it renders diverse structures attainable within one day instead of standard, multi-day syntheses per chromophore.
