反応手順

A solution of catechol (3.30 g, 30 mmol) and xylene (45 ml) was dehydrated by distilling 5 mL of the solution. Thereafter, 6.97 g (20 mmol) of vanadium(III) acetylacetonate was added to the solution while stirring. The mixed solution was refluxed for 1 hour, and then, while the distillation temperature was 132° C. or higher, distilled until the amount of the solution became half. After the distillation, solid content of the product was isolated by suction filtering using a membrane suction filter. The residual solid content was heated to 100° C. under vacuum using a vacuum dryer so that remaining volatile components were completely removed. The solid content (catechol-vanadium complex) was black in color. The yield amount was 4.26 g (20.0 mmol), and the yield percentage was 100%. Catechol-vanadium complex was dissolved into acetylacetone until saturated, and then filtered to be used as a coating liquid.
