Photoinduced electron transfer reactions of 3,3-dialkylated 4,5-diphenyl-3h-pyrazoles: A new route to the formation of the solvent adducts

3,3-Dialkyl-4,5-diphenyl-3H-pyrazoles undergo readily photoinduced electron transfer (PET) reaction with 2,4,6-triphenylpyrylium tetrafluoroborate (TPP+) in acetonitrile to produce cyclopropenes and 2H-pyrroles. During prolonged irradiation, the new ring-closure products derived from 2H-pyrroles as the secondary photoproducts are also produced. However, the corresponding ester analog exhibits different behavior to obtain the cyclopropene as the primary photoproduct and a [2+2] dimer of the cyclopropene as the secondary photoproduct. A rationale for the different behavior is offered.
