실험 절차

A 50-ml round-bottomed flask provided with a magnetic stirrer was charged with 10 mmol of benzaldehyde, 10 mmol of 2-chloro-3,3,4,4-tetramethylcyclobutanone, 12 mmol of a cyanide, 20 ml of n-heptane and 1 ml of water. The rection mixture was stirred vigorously at a temperature of 70° C. Two experiments were carried out in this manner. Table III states the cyanides used and presents the yields of the alpha-cyanobenzyl 2,2,3,3-tetramethylcyclopropane-carboxylate formed.
