The reaction of 1,3-dibromocyclobutane (5) and of 1,3-dibromocyclopentane (6) with magnesium in diethyl ether has been investigated. The corresponding 1,3-di-Grignardreagents 7 (<9%) and 12 (〉〉45%), respectively, were obtained. Compound 12 decomposes to (2-cyclopentenyl)magnesium bromide (13) with a half-life of 5 h. The yields and stabilities of 7 and 12 are briefly discussed.
