摘要：
This invention provides a method for preparing 3,3-dimethylbutyraldehyde from a tert-butyl cation precursor and vinyl chloride. The tert-butyl cation precursor is contacted with vinyl chloride in the presence of an inorganic acid, and the product is allowed to react with water to form 3,3-dimethylbutyraldehyde.
