Abstract endo,exo-Hexacyclo[9.2.02,10.03,8.04,6.05,9]tetradec-12-ene (1) undergoes cyclocodimerization with quadricyclane (Q) in the presence of the Pd(PPh3)4 complex to giveexo,exo,endo,exo-decacyclo[9.9.1.02,10.03,8.04,6.05,9.012,20.013,18.014,16.015,19]heneicosane (2) andendo,exo,endo,exo-decacyclo[9.9.1.02,10.03,8.04,6.05,9.012,20.013,18.014,16.015,19]heneicosane (3) in a ratio of 10 ∶7 (yield up to 26 %). Simultaneously, homocyclotrimerization of Q occurs to give three known C21 hydrocarbons (4–6). The yields of compounds2 and3 and the selectivity of the process depend considerably on the reaction conditions and the molar ratio of1 and Q. Compounds2 and3 that were obtained were characterized by13C NMR spectra.
