The reaction of bicyclic 1,3-diene 1,4-endoperoxides with SnCl2 re-generated the corresponding dienes in 15–70% yield. The efficiency of the deoxygenation depended on the structure of peroxides. The results were compared with those of Fe(II) as well as Pd(O) assisted reactions.

Dichlorocyclopropanation as well as epoxidation of the 1,4-diarylbutadienes 1-4 to give the mono- and/or bisadducts according to several hindrance of large substituents as 2,6-dichlorophenyl. The bisadducts are formed preferably as meso- (or threo-) isomers.
