Chemische Eigenschaften
white solid
Occurrence
Has apparently not been reported to occur in nature.
Verwenden
pinacol 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.
synthetische
By the bimolecular reduction of acetone.
Definition
ChEBI: A glycol that is ethylene glycol in which all four methylene hydrogens have been replaced by methyl groups.
Allgemeine Beschreibung
The pinacol coupling reaction with the inorganic electride [Ca
2N](+)·e(?) as an electron donor in organic solvents was studied.
Stoffwechsel
Pinacol forms a glucuronide in the rabbit (Williams, 1959), and was found highly conjugated with glucuronic acid in the urine of chinchilla rabbits following oral administration of 1.0-1.5 g pinacol/kg body weight (Gessner, Parke & Williams, 1960). Pinacol was not utilized to any significant extent by endocrine tissues from human placenta, rat ovary, rat testis or rat adrenal gland (Ferguson, Baillie, Caiman & Hart, 1966).
läuterung methode
The hydrate is rendered anhydrous by azeotropic distillation of water with *benzene. Recrystallise it from *benzene or toluene/pet ether, absolute EtOH or dry diethyl ether. It recrystallises from water to give the hexahydrate. [Beilstein 1 IV 2575.]
