PREPARATION OF ALLYL ALCOHOLS FROM MONOHALO- AND GEM-DIHALOBUTYLCYCLOPROPANES IN THE PRESENCE OF COPPER AND ITS SALTS

Article abstract of DOI:10.1007/BF00961036

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.
