Versuchsvorschrift

In the same manner as in Example 3, the operation was conducted, except that 0.53 g (2 mmols) of bismethoxymethylbiphenyl was used in place of m-methoxybenzyl alcohol and also 0.2 g (1.35 mmols) of sodium bromate was used. With respect to the components in the reaction solution, 4,4′-bisformylbiphenyl was produced in an area ratio, as determined by gas chromatography, of 93.3% and 6.7% of bismethoxymethylbiphenyl as a raw material was remained.
