## Abstract Irradiation of 1โ€(9โ€phenanthryl)โ€4โ€phenylbutenyne (**1**) in aprotic solvents containing oxygen gives two products, namely a photocyclization product, 1โ€phenyltriphenylene **3**, as is usually formed from diarylbutenynes, and a photooxidation product (2), derived from cyclopropapyrone.

Polymerization of 4-methoxy-4-phenylbut-l-ene and 4-chloro-4-phenylbut-l-ene were undertaken with A1Eh-VC13 as catalyst, under several sets of conditions. Conversion was related to the formation time of the catalytic species, temperature and molar ratio of the components of the catalyst system. Rela

The thermal unimolecular decomposition of hex-1-ene-3-yne (HEY) has been investigated over the temperature range 949-1230 K using the technique of very low-pressure pyrolysis (VLPP). One reaction pathway is the expected c5-c6 bond fission to form the resonance-stabilized 3-ethenylpropargyl radical.
