Photo-irradiation of nine gem-dibromocyclopropanes in ether solution leads to the corresponding monobromocyclopropanes in moderate to good yields. The stereochemical observation indicates that the partial reduction proceeds via an α-bromocyclopropyl radical.

Laserflashphotolysis (LFP) of trans-2-tert-butylcyclopropyldiazirine (4) produces trans-2-tert-butylcyclopropylcarbene (5). Carbene 5 can be trapped with pyridine to form ylide 6. The rate of formation of ylide 6 was resolved and found to be linearly dependent on the concentration of pyridine. The lifetime of carbene 5 was determined to be 22 ns (pentane), 18 ns (acetonitrile and CF2ClCFCl2), 15
