Flash vacuum thermolysis (FVT) of 1-chloro-1-(pyren-1-yl) ethene at 1000° C gives the combustion emittant cyclopenta [c, d] pyrene in good yields; the identification of 1-(pyren-1- yl) ethyne as an intermediate in the range 600–900° C indicates that cyclopenta [c, d] pyrene is formed via an ethynyl–ethylidene carbene rearrangement.
