A New Method of Synthesizing Acenaphthylene

Acenaphthene was dehydrogenated to afford acenaphthylene by photochemical reaction with N bromosuccinimide in benzene with the addition of quinoline at room temperature and atmospheric pressure was studied. Orthogonal test method was used to optimize reaction conditions and the yield of acenaphthylene reached 59.09%. This method is a new one in the synthesizing acenaphthylene under mild conditions.
