3,3-Dialkyl(cycloalkyl)cyclopropenes react with norbornene and norbornadiene at −20°C in the presence of complexes of CuCl with (PhO)3P or Ph3P exclusively by [2 + 2]-cycloaddition, giving the corresponding exo,trans-tetracyclo[5.2.1.02,6.03,5]decanes (or decenes) in yields of 60–94%, the tricyclohexane cyclodimers being obtained in yields of 5–25%.
