The pyrolysis of 1,1,2,4,4-pentaphenyl-1,4-butandiol, trans-1,2-bis(hydroxydiphenylmethyl)hexane, trans-1,2-bis(hydroxydiphenylmethyl)indan, and cis-endo- and trans-1,2-bis(hydroxydiphenylmethyl)bicycloheptane gave styrene, cyclohexene, indene, and norbornene respectively, accompanied by benzophenone and benzhydrol.The pyrolysis of trans-1,2-bis(hydroxydiphenylmethyl)spironona-4,6,8-triene afforded indene via rearrangement to form trans-1,2-bis(hydroxydiphenylmethyl)indan.The pyrolysis of cis-1,1,4,4-tetraphenyl-2-butene-1,4-diol afforded 2,2,5,5-tetraphenyl-2,5-dihydrofuran.On the other hand, trans-1,1,4,4-tetraphenyl-2- butene-1,4-diol afforded 1,2,4,4-tetraphenyl-3-buten-1-one.The mechanisms of these decomposition reactions are discussed.
