Visible light promoted coupling of alkynyl bromides and Hantzsch esters for the synthesis of internal alkynes
Organic & Biomolecular Chemistry(2019)
摘要
A metal-free visible light promoted C(sp(3))-C(sp) coupling reaction of alkynyl bromides and Hantzsch esters was developed, giving internal alkynes with primary, secondary, tertiary alkyl or other functional groups in good to high yields.
