The flow-vacuum pyrolysis of the title diol, between 600°C - 800°C and 1mm Hg in argon atmosphere, was investigated using GC/MS. The main reaction products were: fluorene, 9-methylfluorene, 9-methylenefluorene; 9,10-dihydrophenanthrene; phenanthrene; 9-hydroxy-9,10-dihydroanthracene; 9-fluorenol; 9-fluorenone; 2-methyl-2'-formylbiphenyl (major product; 38% at 850°C); 2-hydroxymethyl-2'-formylbiphenyl and 2,2'-diphendialdehyde. The amount of products resulted from intramolecular cyclization was 52% at 850°C and the ratio between products with five-member and six-member central ring was 39:13 at 850°C. A radical mechanism explaining the formation of the reaction products is suggested and a comparison between pyrolysis of the title diol and of the previously studied 2,2'-bis(bromomethyl)biphenyl is made.
