摘要：

Exploratory laser flash photolysis (LFP) experiments have been performed to determine the feasibility of study of carbene chemistry in supercritical fluids (SCF's). Diphenylcarbene (Ph(2)C:) has been generated by 266 nm LFP of diphenyldiazomethane (Ph(2)CN(2)) in supercritical ethane, carbon dioxide and fluoroform. Diphenylcarbene was found: to react with ethane to form diphenylmethyl radical (Ph(2)C(.)H); to react with CO2 to most likely form diphenyloxiranone; and to be unreactive towards CHF3. The LFP results are discussed in terms of SCF solvent dynamics and the potential of SCF's to influence carbene reactivity.
