See also [1]. To a solution of terephtalaldehyde (2.7g, 20 mmol) and sylvan (8 ml, 100mmol) in 50 ml of benzene 3 ml of Me₃SiCl was added at room temperature. The mixture warmed up to 50-60deg.C within 15 min and a water layer separated. After standing for an additional 15 min, the organic layer was quickly washed with NaHCO₃ solution, separated from the water layer and evaporated to dryness. The residue was recrystallized twice from dioxane. Yield 5.14g (60.25%) of white powder.

M.p. 155-156 deg.C.
