The dihalogenocyclopropane derivative () was obtained in 41% isolated yield when () was treated with an excess of methanesulphonyl chloride and triethylamine in dichloromethane solution; this transformation may be regarded as the retro-reaction corresponding to the silver(I) perchlorate promoted ring-expansion of () to give ().
