OccurrenceHas apparently not been reported to occur in nature.

Usespinacol be used as organic intermediates.The pinacol coupling reaction with the inorganic electride [Ca2N](+)·e(−) as an electron donor in organic solvents was studied. Pinacol is used in the synthesis of organic reagents such as alkenylphenylphosphonates and alkenylboronates.

UsesPinacol is used in the preparation of synthetic intermediates like pinacolborane, bis(pinacolato)diboron and pinacolchloroborane by reaction with boron trichloride. Further, it plays an important role as an intermediate for biologically active compounds like antiviral, antibacterial, antifungal and antituberculous.

General DescriptionThe pinacol coupling reaction with the inorganic electride [Ca2N](+)·e() as an electron donor in organic solvents was studied.

Preparation methods

PreparationBy the bimolecular reduction of acetone.
