Reaction Steps

A solution of 4-nitrocatechol (10 g, 64.5 mmol) and toluene (220 ml) was dehydrated by distilling 20 mL of the solution. Thereafter, 9.15 g (32.2 mmol) of titanium(IV) isopropoxide (TTIP) was added to the solution while stirring. The mixed solution was refluxed for 1 hour, and then, while the distillation temperature was 100° 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 (4-nitrocatechol-titanium complex) was brown in color. The yield amount was 11.0 g (31.1 mmol), and the yield percentage was 97%. 3.54 g of 4-nitrocatechol-titanium complex was dissolved into 100 mL of 1:4 acetylacetone/toluene to produce a coating liquid.
