Versuchsvorschrift

To a mixture of 1.94 g (11.8 mmol) of 2-methyl-1-propenyl phenyl sulfide, 200 mg anhydrous cupric sulfate and 10 ml cyclohexane heated under reflux is added, dropwise and with stirring over a 7 hr period, a solution of 6.58 g (58 mmol) of ethyl diazoacetate in 40 ml cyclohexane. After addition is complete, refluxing and stirring is continued for an additional 2 hr, and then the reaction mixture is filtered, dried and solvent is removed in vacuo to give ethyl 3-phenylthio-2,2-dimethylcyclopropanecarboxylate.
