Reactive Intermediate in the Decomposition Reaction of Bis Diazo Compounds
Dae Dong Sung*, Yoo-Mee Park, Kyu Chul Kim, Dong Kyu Park
Photochemical extrusion reactions of dinitrogen from bis diazo compounds have been carried out by means of laser flash photolysis in argon matrix at low temperature. Photolytic reactions of bis diazo compounds in methanol have been also conducted by using a high-pressure mercury lamp at room temperature. Monocarbenes isolated in the matrix were identified by spectroscopic technique. The spectroscopic result for bis diazo cyclohexanone showed a triplet ketocarbene intermediate at the first step of the loss of nitrogen molecule from the substrate. The continuous decomposition reaction for bis diazo cyclohexanone in methanol at room temperature gave the Wolff rearrangement product.
