Participants

Conditions

Temperature: 90 °C

Procedure

Prepare a reaction vessel from a 1000 mL single neck round bottom flask by fitting with a condenser with a nitrogen inlet. Charge the vessel with 31.55 g 2-(5,5-dimethyl-2-oxido-1,3,2-dioxaphosphinan-2-yl)acetic acid followed by 100 mL water and 4.38 g aluminum hydroxide monohydrate. Heat the resulting solution to 90° C. and hold at that temperature for 24 hours. Isolate the solid by vacuum filtration using a fritted funnel and wash with 400 mL acetone. Transfer the solid product to a glass bottle and place in a vacuum oven to dry overnight. The yield of the solid product of Aluminum tris(2-(5,5-dimethyl-2-oxido-1,3,2-dioxaphosphinan-2yl)acetate) is 31.25 g.
