Described herein is an efficient strategy for assembling a new library of functionalized polycyclic purinium salts with a wide range of anions through RhIII-catalyzed C-H activation/annulation of 6-arylpurine nucleosides with alkynes under mild reaction conditions. The resulting products displayed tunable photo-luminescence covering most of the visible spectrum.nod cl. Mechanistic insights delineated the rhodium catalyst’s mode of action. A purino-isoquinolinium-coordinated rhodium(I) sandwich complex was well characterized and identified as the key intermediate. In the experiment, the researchers used many compounds, for example, Copper(II) trifluoromethanesulfonate (cas: 34946-82-2Recommanded Product: Copper(II) trifluoromethanesulfonate).
Copper(II) trifluoromethanesulfonate (cas: 34946-82-2) belongs to copper catalysts. The transition metal-catalyzed chemical transformation of organic electrophiles and organometallic reagents has turned up as an exceedingly robust synthetic tool. Due to these characteristics, copper nanoparticles have generated a great deal of interest especially in the field of catalysis. Recommanded Product: Copper(II) trifluoromethanesulfonate
