A newly developed ultraviolet photoelectron spectrometer - CO2 laser apparatus that utilizes a 50-watt CW CO2 laser as a directed heat source is used to study the vacuum pyrolysis of 11-oxatricyclo[6.2.1.02.7]undeca-2,9-diene (4). We report the HeI photoelectron spectrum of the strained cyclic allene 1,2-cyclohexadiene (1) that correlates with the HAM/3 ionization energies calculated with the optimized C2 equilibrium structure obtained with AM1 and the molecular orbital energies of the optimized C2 equilibrium structure calculated at the ab initio HF/6-31G** level of theory.
6-BROMO-6-(TRIMETHYLSTANNYL)BICYCLOHEXANE AS A THERMAL PRECURSOR OF 1,2-CYCLOHEXADIENE

Flash vacuum pyrolysis and matrix-isolation studies of 6-bromo-6-(trimethylstannyl)bicyclohexane (1) gave evidence for the formation of 1,2-cyclohexadiene (2) from this precursor.At high temperatures (>600 deg C) 2 is not stable and fragmentates to 1-butene-3-yne (4) and ethylene.
