Abstract
Laboratory instructions for a glove box experiment involving the synthesis of the compound bis(1,2-dimethylimidazole)copper(I) hexafluorophosphate are given. This synthesis (modified from a previous literature article) can be completed in a four-hour lab period and gives students an excellent opportunity to learn basic glove box techniques. Typical student yields average around 65%. Details of needed reagents and supplies used in the glove box are provided, as well as information on solvent purification. A schematic for an in-house vacuum filtration system for use in the glove box is also presented.
Supplement
Instructions for the students and notes for the instructor are available.

 Caution! 
Experiments, laboratory exercises, lecture demonstrations, and other descriptions of the use of chemicals, apparatus, instruments, computers, and computer interfaces are presented in the Journal of Chemical Education as illustrative of new or improved ideas or concepts in chemistry instruction and are directed at qualified teachers. Although every effort is made to assure and encourage safe practices and safe use of chemicals, the Journal of Chemical Education cannot assume responsibility for uses made of its published materials. Many chemicals are hazardous. Precautions for the safe use of hazardous chemicals and directions for their proper disposal are described in the Material Safety Data Sheets and on the labels. We strongly urge all those planning to use materials from our pages to make choices and to develop procedures for laboratory and classroom safety in accordance with local needs and situations.
