Catechol → HCID 66722961, compound

Participants

Reaction Steps

A solution of catechol (22.0 g, 0.20 mmol) and toluene (220 mL) was dehydrated by distilling 20 mL of the solution. Thereafter, 20.8 g (0.10 mmol) of tetraethoxysilane (TEOS) 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 at a liquid flow rate of 15 mL/h until the amount of the solution became 100 mL. As a result, catechol-silicon complex toluene was obtained. To 2 mL of catechol-silicon complex toluene, 2 mL of acetylacetone was added to produce a coating liquid.
