Abstract

The synthesis of the perchloro-9-phenylfluorenyl radical (PPF) from 9-phenylfluorene (1) has been accomplished through a chlorolytic aromatic perchlorination to aH-pentadecachloro-2- biphenylylphenylmethane(2) with BMC reagent, followed by a cyclization at 300 “C (91%). The radical PPF is also obtained by cyclization at 320 “C of the perchlorotriphenylmethyl radical (PTM). Other syntheses of the radical PPF are described. PPF is chlorinated to ...
