Reaction Steps
Chloroform (0.2 moles) was added dropwise with stirring to a solution of 1,1-di-(p-methoxyphenyl)ethylene (0.1 mole) in methyl cyclohexane containing potassium tert-butoxide (0.4 moles) at 0°C. The mixture was allowed to warm to 20°C. overnight and then poured into water. The oil phase was separated and the solvent recovered. The residual solid was recrystallized from petroleum ether to give 1-(p-methoxyphenyl)-1-(p-methoxyphenyl)-2,2-dichlorocyclopropane, m.p. 141°C.
