Cyclopropane dicarboxylic acid esters |
| abstract |
The lower alkyl esters of racemic trans-2,2-disubstituted-1,3-cyclopropanedicarboxylic acids are prepared by reaction of a triphenylphosphonium with an alkyl fumarate or maleate. The esters are intermediates which are useful especially for the preparation of aldehydes themselves leading to pyrethrinoid derivatives having insecticidal properties. <IMAGE> |
