Abstract Photolysis of the title bis-diazirine matrix-isolated in Ar at 10 K monitored by IR and UV/vis spectroscopy indicated that the diazirine underwent stepwise elimination of N2 to produce 3-(4-chlorocarbenophenyl)-3-chlorodiazirine which then eliminated the second N2 to generate para-phenylenebis(chloromethylene). The structure of the bis-carbene was discussed based on the spectroscopic data as well as the semiempirical theoretical calculations.
