This study detected the extremely reactive carbenoid, 1,2,3‐hexatriene‐5‐one (HTO), by low‐temperature atmospheric pressure ionization (API) mass spectrometry. During the analysis the sample solution was maintained at −78 °C in the API source to prevent the analyte molecule from polymerizing. At this low temperature a strong protonated HTO signal was detected. At room temperature the compound polymerized rapidly and the mass spectrum was dominated by dimer ions. Signals due to protonated HTO‐ (H 2 O) 2 adducts were also detected, and can possibly be attributed to trace water in the organic solvent, or to ionization of the moisture as in atmospheric pressure chemical ionization. © 1998 John Wiley & Sons, Ltd.
