## Abstract The title reactions have been investigated in a static system. The addition of acetylene to cyclopentadiene (CPD) results in formation of norbornadiene (BCH), cycloheptatriene (CHT), and toluene (T), while BCH decomposition produces CPD, C~2~H~2~, CHT, and T. Kinetic studies, comprising
Irradiation of 1-phenylphosphole oxide-cyclopentadiene adduct gave a caged product, whereas similar irradiation of 1,2,5-triphenylphosphole oxidecyclopentadiene adduct afforded a cleavaged product. Previous studies 2) from this laboratory showed that the Diels-Alder dimer of 1-phenylphosphole oxide
