Versuchsvorschrift

Alternately, when no catalyst is used, the reaction is carried out at a higher temperature (approx. 150° ) for thermal decomposition. Xylene is heated to reflux and a mixture of 2-methyl-1-propenyl phenyl sulfide and ethyl diazoacetate is added dropwise over 2 hr. Reflux is continued an additional 1 hr or until nitrogen evolution has ceased. The reaction is then filtered, dried and solvent is removed, giving ethyl 3-phenylthio-2,2-dimethylcyclopropanecarboxylate.
