A new process that could directly prepare α-haloacetal of ketones from various ketones with N-halosuccinimide (NBS/NCS) and ethylene glycol in one step without any other catalysts was reported. The effects of solvents, NBS/NCS and reaction temperature were investigated. Under the optimal condition, most of α-haloacetals of ketones were obtained in 90–100% yield.

The positions of the conformational equilibria in a series of 2-substituted cyclohexanone ketals have been determined by 1H NMR.For the ethylene ketals 6 the equatorial conformer has been found to be enthalpically preferred.The other ketal syst
