Laser flash photolysis of alkylphenyldiazomethanes in the presence of pyridine produces easily detected ylides. The data indicate that photolysis of alkylphenyldiazomethanes leads to both carbene formation and direct formation of rearrangement products which do not derive from relaxed carbene intermediates

At 25°, photolytically generated cyclopropylphenylcarbene affords phenylcyclobutene (63%, by ring expansion), phenylacetylene (16%, by fragmentation), and only traces (<3%) of the adduct to isobutene; at lower temperatures, however, the latter compound becomes the major product.
