Abstract

1,214,527. Polycyclic polyenes. SNAM PROGETTI S.p.A. 8 March, 1968 [13 March, 1967], No. 11558/68. Heading C5E. The invention comprises substituted orthocondensed polycyclic polyenes containing at least one conjugated alkylidene substituent and at least one bridged carbon ring, which have been produced by the condensation of a conjugated cyclic diene with a fulvene derivative. 1 - Isopropylidene - dicyclopentadiene is prepared by reacting cyclopentadiene with 6,6- dimethylfulvene.
