Salaun, J. published the artcileSmall rings. XXX. Ring expansion of cyclopropanols. 1-(Halomethyl)-, 1-(hydroxymethyl)-, 1-vinyl-, 1-acylcyclopropanols, and oxaspiropentanes to cyclobutanones, Safety of (1-Bromocyclopropyl)methanol, the publication is Tetrahedron (1974), 30(11), 1413-21, database is CAplus.
1-(Hydroxymethyl)-, 1-(tolysulfonyloxymethyl)-, 1-(bromomethyl)cyclopropanol, and oxaspiropentane (I), prepared from methylenecyclopropane, underwent ring expansion to form cyclobutanones. 1-Vinyl-, 1-(1-cyclopentenyl)- and 1-(1-cyclohexenyl)cyclopropanol, prepared from (ClCH2)2CO underwent similar ring expansion. 1-Cyclopropylcyclopropanol under similar conditions gave cyclopropyl Et ketone. II with NaOMe followed by treatment with ClSiMe3, gave cyclobutanone III.
