Alternate Name: IPr.

Solubility: soluble in THF, hexane, toluene, ether, and most organic solvents.

Analysis of Reagent Purity: elemental microanalysis, NMR spectroscopy.

Preparative Methods: can be prepared under inert atmosphere3 utilizing dry, oxygen-free solvents.4 IPr·HCl2 and KOtBu were added to a NaH suspension in THF in the glove box (eq 1). The mixture was stirred for 1 h at room temperature, for 2 h at 60 °C, followed by overnight stirring at room temperature. THF was removed in vacuo, the product was extracted with hot hexanes, filtered through a pad of Celite, and the solvent removed in vacuo resulting in a white solid.2
