Koester, Roland published the artcileReactions of methylenecyclopropane. I. Halogenation, hydrohalogenation, and hydroxybromination, Synthetic Route of 50915-29-2, the publication is Justus Liebigs Annalen der Chemie (1973), 1619-27, database is CAplus.
The reactions of methylenecyclopropane with Cl, Br, HCl, HBr, and HOBr at 0 to -78° were investigated. The influence of LiBr, hydroquinone, and Bz2O2 on the halogenations and of Lewis acids, e.g., FeCl3 or SnCl4, on the hydrohalogenations was examined With Cl and HCl ring opening predominated, yielding CH2:C(CH2Cl)2 and CH2:CMeCH2Cl, resp. Reaction with Br preferentially afforded 1-bromo-1-(bromomethyl)cyclopropane (I). Hydroxybromination gave only 1-bromo-1-(hydroxymethyl)cyclopropane (II). Reduction of I or the tosylate of II with NaBHEt3 gave 1-bromo-1-methyl-cyclopropane.
