SYNTHETIC METHOD OF 7-DIMETHYLAMINO-2,2-DIMETHYL-6-ENE-3,5-SUBERICALDEHYDE-0,0-BORON DIFLUORIDE

摘要

A synthetic method of 7-dimethylamino-2,2-dimethyl-6-ene-3,5-subericaldehyde-0,0-boron difluoride is provided. The method includes the following steps: adding N,N-dimethylacetamide dimethyl acetal to an anhydrous solution containing N,N-dimethylacetamide, 2,6-dimethylpyridine and 5,5-dimethyl-2,4-adipaldehyde-0,0-boron difluoride under 20-50?; stirring for 2-5h and then reacting for 2-24h under 80-100?; cooling under -10-0?; separating the product and washing by organic solvent to obtain 7-dimethylamino-2,2-dimethyl-6-ene-3,5-subericaldehyde-0,0-boron difluoride.
