Participants

Reaction Steps

1-Chloro-3-(spiro[3.3]hept-2-yl)-1E-propen-3-one (7.3 g, 0.042 mole) was mixed with 25.2 g (0.168 mole) of sodium iodide and 45 ml of dry acetone (distilled from anhydrous potassium carbonate, b.p. 56° C). The mixture was refluxed with rapid stirring overnight. The mixture was cooled and the solvent was removed in vacuo. The solid residue was taken up in 75 ml of water and the products were extracted with 150 ml (3×50 ml) of ether. The organic material was washed with 50 ml of saturated sodium bicarbonate solution, 50 ml of aqueous sodium thiosulfate solution and 50 ml of saturated sodium chloride solution. The material was dried over anhydrous magnesium sulfate, filtered and the solvent was removed in vacuo to yield 6.9 g (62.2%) of crude 1-iodo-3-(spiro[3.3]hept-2-yl)-1E-propen-3-one.
