7,7-二氯二环[3.2.0]庚-2-烯-6-酮

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

实验步骤: Over a period of 1.5 hr 21.7 g of dry triethylamine in 200 ml of hexane was added to a vigorously stirred solution mixture of 27.2 g of freshly distilled cyclopentadiene (I), 30.5 g of dichloroacetyl chloride, and 200 ml of hexane (dried over molecular sieves). After stirring for 15 hours under an atmosphere of nitrogen, the reaction mixture was filtered and the filter cake was washed with hexane. The solvent was removed under vacuum, yielding a 35.2 g of liquid, which, when redistilled under vacuum, afforded 30 g of 7,7-dichlorobicyclo(3.2.0)hept-2-en-6-one (II). the reaction mixture was filtered the filter cake was washed with hexane The solvent was removed under vacuum
