MeCN in the Presence of 4-ChlorobutyryI Chloride (lb, Method B). The substrate (0.6 g, 2.33 mmol) is reduced at -1.78 ± 0.08 V in the presence of lb (0.27 mL, 2.4 mmol): = 2.21; crude product, 0.685 g. The first time, the chromatographic column is eluted with benzene; 13b (23%) and 14d (9%) are thus isolated. Then the column is eluted with diethyl ether, and 0.415 g of a mixture of four compounds is collected. In a second experiment, the column is eluted with 70:30 diethyl ether-hexane, and 15d (20%), 10c (6%), and 15c (8%) are isolated. At least, 19 (5%) is collected from the column with diethyl ether as the eluant., -Diphenyl-a-anilinoacetylcyclopropane (14d): mp 157
