of (Z)- and (E)-1,2-di(1-adamantyl)ethene (1a and 1b, respectively) is reported. Compound 1a reacts with dichlorocarbene to afford (Z)-1-[3-(dichloromethyl)-1-adamantyl]-2-(1-adamantyl)ethene (2, 27%), (Z)-2,3-dichloro-1,3-di(1-adamantyl)propene (3, 20%) and 1,1,2-trichloro-2-(1-adamantyl)chloromethyl-3-(1-adamantyl)cyclopropane (4, 21%). The corresponding reaction of 1b produced and (E)-1,2-di[3-(
