                                    Photolysis of pentafluorophenyl azide in n-butane, cyclopentane, or 2,3-dimethylbutane releases singlet (pentafluorophenyl)nitrene, which can insert into a CH bond, ring expand to a ketenimine, or undergo intersystem crossing (ISC) to the triplet state of the nitrene.  In alkanes at 25-degrees-C ring expansion is the major process, CH insertion is only modest, and ISC is unimportant.  At temperatures below -78-degrees-C, ISC is the dominant process.  Differential activation parameters are derived and compared with those of phenyl azide.
