• Laser flash photolysis of 3-(4-biphenylyl)-2<I>H</I>-azirine (AZ) was carried out in cyclohexane for the direct detection of a nitrile ylide (NY). Two kinds of transient species, triplet AZ (T<SUB>1</SUB>) and NY, have been measured. Decay rates of these species were determined to be 6.7×10<SUP>5</SUP> s<SUP>−1</SUP> (T<SUB>1</SUB>) and 8×10 s<SUP>−1</SUP> (NY). The rate constants for the reactions of NY toward acetone and acrylonitrile were determined to be 2.5×10<SUP>3</SUP> dm<SUP>3</SUP> mol<SUP>−1</SUP> s<SUP>−1</SUP> and 2.3×10<SUP>6</SUP> dm<SUP>3</SUP> mol<SUP>−1</SUP> s<SUP>−1</SUP>, respectively. These results were supported by the results of pulse radiolysis of AZ in benzene and stational irradiations of AZ.
