PROCESS FOR PRODUCING TETRAFLUORO BENZENECARBALDEHYDES AND TETRAFLUORO BENZENEMETHANOLS |
摘要 |
<p>The present invention relates to a process by a series of reactions using tetrafluorocyanobenzens as material for producing tetrafluorobenzenemethanols, tetrafluorobenzenecarbaldehyde dialkylacetals and tetrafluorobenzenecarbaldehydes in a high purity and a high yield which are useful as intermediates in the production of cyclopropanecarboxylic acid esters having insecticidal action, and also relates to a novel tetrafluorobenzenecarbaldehyde dimethylacetal.</p> |
