实验步骤: Six batches of ethylfurfuryl ether comprising liquid were prepared as follows. A feed mixture of 120 grams ethanol and 110 grams furfuryl alcohol (molar ratio ethanol/furfuryl alcohol of 2.5) was added to 10 grams acidic ZSM-5 particles with a silica-alumina ratio of 30. The mixture was contracted with the catalyst for 2.5 hours at 125° C. under stirring. was added to 10 grams acidic

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: Pentachlorocyclopropane (25 g, 0.116 mol) is added to a suspension of potassium hydroxide (7.8 g, 0.139 mol) in 1,4-dioxane (900 ml) and the mixture is stirred at room temperature for 30 minutes and then heated to 65° C. for a further 30 minutes. 2-Ethoxymethylfuran (17.5 g, 0.139 mol) is added to the reaction mixture, the temperature is raised to 85-90° C. and the mixture is stirred for 16 hours. The reaction mixture is cooled to room temperature, filtered through a plug of diatomaceous earth and the filtrate is evaporated under reduced pressure to give (1S*,5S*)-2,3,4,4-tetrachloro-1-ethoxymethyl-8-oxabicyclo[3.2.1]octa-2,6-diene (23 g), used without further purification in the next step. heated to 65° C. for a further 30 minutes the temperature is raised to 85-90° C. the mixture is stirred for 16 hours The reaction mixture is cooled to room temperature filtered through a plug of diatomaceous earth the filtrate is evaporated under reduced pressure
