Cyclobutene reacted with dibromocarbene in solution to give 1,5-dibromocyclopent-1-ene (9), 1,2,6, 6-tetrabromobicyclo[3.1.0]hexane (10), and 1,2,3,6-tetrabromocyclohex-1-ene (11), in a ratio of 1:4:8, respectively. Compounds 10 and 11 were found to be formed from a second carbene addition and rearrangement under the given reaction conditions.

New dichloro- and dibromocarbene addition-rearrangements are reported. In the reactions of 1,2-diarylcyclopropenes with difluoro-, dichloro-, dibromo-, and bromofluorocarbene, 2,3-diaryl-1,1-dihalo-1,3-butadienes are formed. In addition, 1,3-diaryl-2,3-dihalocyclo-1-butenes are formed. For the formation of the 1,1-dihalobutadienes, new addition-rearrangement mechanisms are proposed. Furthermore, some reactions of cyclobutenes with dihalocarbenes are described.
