TEMPERATURE AND MATRIX EFFECTS ON MULTIPLICITY-SPECIFICITY AND C-H INSERTION SELECTIVITY IN REACTION OF PHENYLCARBENE

Article abstract of DOI:10.1246/cl.1980.293

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.
