Pinacol Chemical Properties,Uses,Production
Chemical Properties
white solid
Occurrence
Has apparently not been reported to occur in nature.
Uses
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.
Preparation
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ChEBI: A glycol that is ethylene glycol in which all four methylene hydrogens have been replaced by methyl groups.
General Description
The pinacol coupling reaction with the inorganic electride [Ca2N](+)·e(?) as an electron donor in organic solvents was studied.
Metabolism
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).
Purification Methods
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.]
