What is QUINUCLIDINE?
The Uses of QUINUCLIDINE
Quinuclidine acts as a catalyst, a chemical building block and is used in organic synthesis. It is employed to prepare quinine and alkaloids. It finds application as a ligand, which is useful in the studies of OsO4-catalyzed dihydroxylation of olefins. It plays an important role in the formation of onium salts used testing of PAC-antagonist activity.
Definition
ChEBI: Quinuclidine is a saturated organic heterobicyclic parent and a member of quinuclidines.
Hazard
A poison by ingestion and skin contact. Low toxicity by inhalation. A moderate skin and severe eye irritant.
Purification Methods
Crystallise it from diethyl ether. The hydrochloride has m 364-365o(dec) (from EtOH or n-BuOH), and the picrate has m 225o (from aqueous EtOH). [Beilstein 20 H 144, 20 II 71, 20 III/IV 1966, 20/4 V 335.]
