Bromoalkoxyethylenes were prepared by the action of zinc and alcohol on dibromoacetals in the same way that alkenes are obtained from P-bromoether~.~ When the starting material was the dibutyl acetal, a mixed acetal of monobromoacetaldehyde, BrCH2CH (OC2Hb) OC4H9, was obtained as a by-product, apparently by the addition of a molecule of alcohol to bromobutoxyethylene. When a large run was attempted this mixed acetal was the ...
