Zusammenfassung: | anti‐1,2‐Dizincation of arylacetylenes has been achieved through electron injection using sodium dispersion and immediate transmetalation with a zinc chloride TMEDA complex. The resulting dizincated alkenes then undergo the Negishi cross‐coupling with the aid of additional zinc chloride to yield multi‐substituted alkenes with high stereoselectivity. The overall transformation provides a new approach for anti‐selective diarylation of alkynes. More details can be found in article number e202400384 by Hideki Yorimitsu and co‐workers. |
