Abstract
Dimerization of cycloheptatriene, catalyzed by titanium complexes, afforded pentacyclo[8.4.0.03,7.04,14.06,11]tetradeca-8,12-diene (I) (10%) and pentacyclo[7.5.0.02,8.05,14.07,11]tetradeca-3,12-diene (II) (90%). Structure of both dimers and their derivatives was determined by means of 1H NMR, 13C NMR and mass spectra. On heating, the diene II was converted into the more stable isomer I. On hydrogenation and further catalytic isomerization, both I and II gave diamantane in high yield.Keywords
