• The pyrolysis of 1,1,2,4,4-pentaphenyl-1,4-butandiol, <I>trans</I>-1,2-bis(hydroxydiphenylmethyl)hexane, <I>trans</I>-1,2-bis(hydroxydiphenylmethyl)indan, and <I>cis</I>-<I>endo</I>- and <I>trans</I>-1,2-bis(hydroxydiphenylmethyl)bicyclo[2.2.1]heptane gave styrene, cyclohexene, indene, and norbornene respectively, accompanied by benzophenone and benzhydrol. The pyrolysis of <I>trans</I>-1,2-bis(hydroxydiphenylmethyl)spiro[2.6]nona-4,6,8-triene afforded indene <I>via</I> rearrangement to form <I>trans</I>-1,2-bis(hydroxydiphenylmethyl)indan. The pyrolysis of <I>cis</I>-1,1,4,4-tetrapheny 1-2-butene-1,4-diol afforded 2,2,5,5-tetraphenyl-2,5-dihydrofuran. On the other hand, <I>trans</I>-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.
