Carbocyclic three-, four- and five-membered rings are formed in good to excellent yield (87–100%) upon treatment of the appropriate α,ω-diiodide with t-butyllithium in pentane-ether solution at −23°C. The corresponding dibromides do not undergo clean cyclization.

The anodicoxidations of polyalkyl-substituted cyclopropanes (1–3) and spiro[2.n]alkanes (4–6) were carried out in methanol. Monomethoxyolefin and dimethoxy compound resulted from the selective cleavage at the most substituted carbon–carbon bond. The decrease in the oxidation potential brought about by the substitution of the one methyl group was observed to be about 0.3 V vs. SCE. The analysis of

AbstractEight alkylcyclopropane derivatives were prepared in a conventional manner and analysed by 13C NMR spectroscopy. Additivity parameters were calculated from the chemical shifts of the endocyclic carbons, and the configurational structures derived for these compounds are confirmed by the internal coherence found for this set of parameters.
