摘要

There has already been discussion concerning the fact that a conjugated planar cyclic en- yne system may form a continuous molecular ж-orbital overlapping the^-orbitais of the carbon atoms of the unsaturated linkages in the cycle15. It is of interest to synthesize such a cyclic acetylene in order to establish experimentally the validity of the theoretical prediction, but the only member of this series known up to now is the completely conjugated planar ...
