Figure (image) Kanazawa University Share Print E-Mail Caption The first photocatalytic active alkyne generation from a cyclopropenone under visible light conditions has been achieved. The generated active alkynes such as ynamine and cyclooctyne can be directly used, without isolation, for the chemical reactions such as a dehydration condensation and alkyne-azide click chemistry.
