The C42H32 hydrocarbon formed by acid-catalysed dehydration of 1,1,3-triphenylprop-2-en-1-ol is shown to be 1,3-diphenyl-2-(1,3,3-triphenylprop-2-enyl)indene, and not a cyclobutane derivative as has been proposed. Condensation of benzaldehyde with 1,1-diphenylethylene gives either 1,1,3,5,5-pentaphenylpenta-1,4-diene or the above-mentioned indene, and not a cyclobutane derivative as previously proposed.
