Abstract
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)bicyclo[2.2.1]heptane gave styrene, cyclohexene, indene, and norbornene respectively, accompanied by benzophenone and benzhydrol. The pyrolysis of trans-1,2-bis(hydroxydiphenylmethyl)spiro[2.6]nona-4,6,8-triene afforded indene via rearrangement to form trans-1,2-bis(hydroxydiphenylmethyl)indan. The pyrolysis of cis-1,1,4,4-tetrapheny 1-2-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.
