Process for preparing cyclopropane carboxylic acids |
摘要 |
1-Cyano-3-[2',2'-(dihalogeno and/or trifluoromethyl)vinyl]-2,2-dimethylcyclopropanes are converted into the corresponding 1-amides and 1-carboxylic acids by reaction with sulphuric acid and water, or into the corresponding 1-carboxylic acid esters by reaction with sulphuric acid, water and a lower alkanol. High yields are obtained.
