Ring formation via an intramol. Grignard coupling reaction of trihalo alkanes is presented. 2-Methyl-2-(chloromethyl)-1,5-dichloropentane was prepared and treated with two equivalent Mg in THF to study the possible ring formation through 1,5 and/or 1,3 coupling reactions. A 1,3 Grignard coupling reaction was shown to occur preferentially, and a cyclopropane derivative I was formed. A 1,5 coupling reaction could not be realized under the prevailing reaction conditions. A diradical mechanism for the Grignard coupling reaction is proposed to account for the behavior of this compound and other similar polymetallophilic systems in their reaction with Mg.
