Catechol → Zirconium Catecholate

Participants

Reaction Conditions

Reaction Steps

A solution of catechol (2.20 g, 20 mmol) and toluene (25 ml) was dehydrated by distilling 5 mL of the solution. Thereafter, 5.00 g (10.6 mmol) of zirconium(IV) isopropoxide 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 (catechol-zirconium complex) was black in color. The yield amount was 3.07 g (10.0 mmol), and the yield percentage was 100%.
