Process for the preparation of arylacetaldehyde-dialkylacetals |
摘要 |
Arylacetaldehyde-dialkylacetals are prepared with high yields and selectivity from the corresponding chloromethylaromatics in the presence of hydrogen chloride acceptors and methyl carbonyl compounds as catalysts and in the presence of orthoesters as water-binding agents by hydroformylation with carbon monoxide and hydrogen.
