反应详情

20 mL of 2-mesitylmagnesium bromide (1.0 M in diethyl ether, 20 mmol) was added to a flask containing 60 mL of dry diethyl ether and solid carbon dioxide (dry ice). Additional dry ice was added throughout the course of the reaction as needed. After 30 min, the mixture was allowed to warm to room temperature and the solid was separated by filtration. The solid was dissolved in a 1 M KOH(aq) solution followed by neutralization to pH 1 using HCl. This resulted in the precipitation of a white powder that was collected by filtration and dried under vacuum at 80° C. (2.52 g, 77% yield).
