Ethyl orthoformate → HCID 85410153, compound

Participants

Reaction Steps

A mixture of 3-cyclopropyl-1-(4-pentafluorosulphanylphenyl)-propan-1,3 -dione (0.82 g) and triethylorthoformate (3.1 g) in acetic anhydride (40 ml) was heated at reflux temperature for 6 hours. The excess reagent and solvent were evaporated to give 3-cyclopropyl-2-ethoxymethylene-1-(4-pentafluorosulphanylphenyl)-propan-1,3 -dione (1.0 g) as an orange oil. This was used directly in the subsequent reaction stage.
