## Abstract __cis__‐ and __trans__‐(3,6‐D~2~)‐1,4‐cyclohexadienes **1a** and **1b** have been synthesized from __cis__‐3,4‐dichlorocyclobutene (5). Aromatization to benzene with DDQ is __cis__‐stereospecific with an uncertainty of 5%. This result is discussed in relation to concerted or stepwise me
