indium(3+);triacetate

Conditions: temp:100.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A solution of catechol (3.30 g, 30 mmol) and xylene (90 ml) was dehydrated by distilling 10 mL of the solution. Thereafter, 5.84 g (20 mmol) of indium acetate 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, volatile components of the residual mixed solution were vaporized under reduced pressure by a rotary evaporator. The residual solid content was further heated to 100° C. under vacuum using a vacuum dryer so that the remaining volatile components were completely removed. The solid content (catechol-indium complex) was green in color. The yield amount was 5.54 g (20 mmol), and the yield percentage was 100%. 6.93 g of catechol-indium complex was dissolved into 100 mL of 1:4 acetylacetone/toluene to produce a coating liquid. by distilling 10 mL of the solution The mixed solution was refluxed for 1 hour was 132° C. higher, distilled until the amount of the solution After the distillation, volatile components of the residual mixed solution were vaporized under reduced pressure by a rotary evaporator were completely removed 6.93 g of catechol-indium complex was dissolved into 100 mL of 1:4 acetylacetone/toluene to produce a coating liquid
