Abstract

Photochemical studies of phenyldiazomethane in 2-chloropropane as a function of temperature reveal that C–Cl insertion of singlet phenylcarbene is dominant at lower temperature as long as the solvent is liquid, but primary C–H insertion becomes near- exclusive in a rigid matrix, suggesting that two kinds of matrix effect are operating.
