Click chemistry promoted by graphene supported copper nanomaterials.
A facile and robust approach is provided for the synthesis of highly dispersed copper nanoparticles immobilized onto graphene nanosheets, useful as a recyclable and reusable heterogeneous catalyst with excellent catalytic activity to achieve Cu(I)-catalyzed [3+2] cycloaddition 'click' chemistry.
متن کاملThiacycloalkynes for Copper-Free Click Chemistry**
Bioorthogonal chemistry enables the interrogation of biomolecules and physiological processes that are inaccessible by using conventional research tools. A common experimental protocol starts by labeling a target biomolecule in cells or live organisms with a bioorthogonal functional group. Then, a probe molecule bearing complementary functionality is added to the system and the ensuing bioortho...
متن کاملCopper-free click chemistry in living animals.
Chemical reactions that enable selective biomolecule labeling in living organisms offer a means to probe biological processes in vivo. Very few reactions possess the requisite bioorthogonality, and, among these, only the Staudinger ligation between azides and triarylphosphines has been employed for direct covalent modification of biomolecules with probes in the mouse, an important model organis...
متن کاملGenetically Encoded Copper-Free Click Chemistry**
The ability to visualize biomolecules within living specimen by engineered fluorescence tags has become a major tool in modern biotechnology and cell biology. Encoding fusion proteins with comparatively large fluorescent proteins (FPs) as originally developed by the Chalfie and Tsien groups is currently the most widely applied technique. As synthetic dyes typically offer better photophysical pr...
متن کاملReusable and highly active supported copper(I)-NHC catalysts for Click chemistry.
Immobilised [Cu(NHC)] catalysts are reported for the preparation of 1,2,3-triazoles. In addition to showing outstanding catalytic activity, the catalyst systems are easy to prepare and can be recycled many times.
