【Abstract】 Tetramethylethylene was prepared from isopropyl chloride through Grignard reaction and dehydration catalyzed by sulfuric acid. It reacted with dichloroacetyl chloride to give chlorotetramethylcyclobutanone, and hydrolyzed to tetramethylcyclopropanecarboxylic acid. Fenpropathrin was synthesized from tetramethylcyclopropanecarboxylic acid or chlorotetramethylcyclobutanone.更多还原
