1,6-橋亞甲基[10]輪烯是一種芳香烴，化學式為C₁₁H₁₀。它是第一個被發現具有芳香性的環癸五烯衍生物。

製備

首先通過伯奇還原反應，將萘還原成1,4,5,8-四氫萘，然後與二氯卡賓（由氯仿與叔丁醇鉀反應產生）發生加成反應，生成三元環。之後，產物再次被還原，脫去氯原子，最後用2,3-二氯-5,6-二氰對苯醌（DDQ）移除中間的一根鍵並脫氫，產生1,6-橋亞甲基[10]輪烯。^[3]

芳香性

1,6-橋亞甲基[10]輪烯是環癸五烯（[10]輪烯）的衍生物，其中兩個氫原子被橋聯亞甲基（-CH
2-）取代。它早在1964年就被發現，^[1]^[4]是第一個被發現具有環癸五烯芳香環的化合物。^[5]

受到橋聯亞甲基的影響，1,6-橋亞甲基[10]輪烯的結構扭曲，[10]輪烯骨架中的10個碳原子不在同一平面內。照理來說，原子們需處於同一個平面才會有芳香性，但不符合這一條件的1,6-橋亞甲基[10]輪烯仍具有芳香性。^[6]^[5]1,6-橋亞甲基[10]輪烯的X射線分析與核磁共振譜發現其中碳-碳鍵鍵長沒有交替變化，確認了其芳香性。^[7]

1,6-橋亞甲基[10]輪烯的共振能低於萘。^[8]

應用

1,6-橋亞甲基[10]輪烯已用於生產導電聚合物。^[9]
