The photochemistry of phenyldiazomethane in cyclohexene (cyclohexene-d10) and cyclohexane (cyclohexane-d12) was studied.The chemistry observed was found to be entirely consistent with singlet rather than triplet phenylcarbene reactions.Small (1.9-2.1) isotope effects to CH insertion were observed at 25 deg C that increased on cooling.Cooling to very low temperature (-196 deg C) reduced the isotope effect.The results are discussed in terms of the hardness of the polycrystalline solid matrix.
