A controlled/"living" click polymerization method developed by researchers at the Institute of Science Tokyo and Nagoya ...

Controlling regioselectivity remains one of the major challenges in hydrocyanation. When an unsymmetrical alkyne undergoes ...

This protocol is for the ultrasound (US)-assisted 1,3-dipolar cycloaddition reaction of azides and alkynes using metallic copper (Cu) as the catalyst. The azido group is a willing participant in ...

An azide group reacts with an alkyne group to form a five-membered ring. However, this reaction requires a toxic copper catalyst, making it unsuitable for living systems.
