Abstract

Treatment of ozonides or aldehydes with a mixture of dihalomethane and diethylamine in dichloromethane affords α-substituted acroleins in good yields, the β-carbon of the acrolein being derived from dihalomethane; the relative rates and yields are in the following order: CH2l2> CH2Br2> CH2Cl2.
