Photoelectron spectra of six 8,11-disubstituted pentacycloundecanes (1, 3 -7) are reported; the results suggest that the through-space interaction betweeen unsaturation centers in 1 and 3 dominates over the through-bond interaction mechanism.
We wish to report the synthesis, reactions, and photoelectron spectrum of 8,LL-dimethylenepentacyclo (5.4.0.0 2,6,03,10\_05,9 ]tridecane (A), a potential precursor of a derivative of the (2.2.2)propellaneL (2). Another interesting aspect of 1 is the unique spatial arrangement of

The standard molar energy of combustion of pentacyclo[5.4.0.0 2,6 .0 3,10 .0 5,9 ]undecane-8,11-dione has been determined by using a static bomb calorimeter. The vapour pressure of the compound was measured in the interval T = 325.64 K to T = 340.97 K by the Knudsen-effusion technique. Enthalpy of f
