Abstract
Irradiation of 3,3-cyclopentyl-3H-pyrazole yields spiro[2,4]hept-1-ene , vinylidenecyclopentane, and 1-vinylcyclopentene by direct intramolec ular rearrangements from the excited diazoalkene (54%) and by competit ive formation and subsequent rearrangement of the corresponding vinylc arbene.
