The unusual 1,4‐addition of singlet dihalocarbenes to 1,3‐dienes to give 3 occurs, in the case of the cis ‐fixed 1,3‐diene 1 , with almost equal justification as the usual 1,2‐addition to give 2 . The type of generation of the dihalocarbenes CCl 2 and CBr 2 plays no decisive role regarding the 2 : 3 ratio.
