## Abstract Transition‐metal‐catalyzed dimeric coupling–cyclization reactions of two different 2,3‐allenols afforded 4‐(1′,3′‐dien‐2′‐yl)‐2,5‐dihydrofuran derivatives **3**. 2‐Substituted 2,3‐allenols **1** cyclized to form the 2,5‐dihydrofuran ring, whereas the 2‐unsubstituted 2,3‐allenols **2** p
4-(2%-Alkenyl)-2,5-dihydrofurans can be efficiently synthesized via the PdCl 2 -catalyzed coupling-cyclization of allylic halides with 2,3-allenols in DMA at rt in moderate to good yields. The regioselectivity is different from that of the Pd(0)-catalyzed coupling-cyclization of organic halides with
