Isomerization of crystalline 1,2,3-tris(arylmethylene)cyclohexanes to 1,2,3-tris(arylmethyl)benzenes by gaseous hydrogen bromide

1,2,3-Tris(arylmethylene)cyclohexanes (eleven examples) are prepared by aldol condensation from aromatic aldehydes and cyclohexanones, followed by Wittig olefination. They are rearranged nearly quantitatively by gasous hydrogen bromide to 1,2,3-tris(arylmethyl)benzenes.
