摘要:
The reaction of gem-dibromo- or gem-dichlorobutylcyclopropanes with an equimolar amount of CuSO4 . 5H2O in a mixture of DMSO and water is accompanied by scission of the three-membered ring and formation of the corresponding 2-bromo- or 2-chloroallyl alcohols. The corresponding allyl alcohols were prepared analogously from monobromo- or monochlorocyclopropanes.
