The previously observed cyclopropaoation of alkenes by irradiation of diiodomethane (I) in their presence has been studied in more detail and found to be a synthetically useful procedure which is significantly less subject to steric effects than the traditional Simmons-Smith method. The results from photocyclopropanation of a variety of alkenes are summarized in Tables 1 and 3–4. In a number of cases

Reaction between bis(cyclopentadienyl)titanacyclobutanes (1) and tetrakis(trifluoromethyl)cyclopentadienone (2) results in formal reductive elimination of cyclopropanes and activation of an sp3 C–F bond in (2) to afford the novel organometallic product (3)(structurally characterized by X-ray crystallography).

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.
