A novel PVP-I catalyzed acetalizations/transacetalizations of carbonyl compounds has been developed processing with a mild and easy handling fashion. Different types of Acyclic and cyclic acetals were prepared from carbonyl compounds or their acetals successfully. Further applications of newly developed catalytic combination were testified. This protocol featured with simplicity of operation, mild reaction condition, short reaction time, recyclable of catalyst and broad substrates scope with excellent yields.

When methoxide ion attacks an unsubstituted 2- or 6-position of a 3-trichloromethylpyridine, a hydrogen shift leads to a methoxy-substituted 3-dichloromethylpyridine. Further reaction of the dichloromethyl group with methoxide gives the corresponding acetal. This type of reaction has been applied to several chlorinated 3-trichloromethylpyridines and to 3- trichloromethylpyridine itself; a convenient synthesis of the latter is described.
