4,4'-Bipyridine Chemical Properties,Uses,Production

Chemical Properties

off-white to tan powder

Definition

ChEBI: A bipyridine in which the two pyridine moieties are linked by a bond between positions C-4 and C-4'.

Synthesis Reference(s)

Tetrahedron Letters, 26, p. 1655, 1985 DOI: 10.1016/S0040-4039(00)98576-9

Safety Profile

Poison by ingestion. When heatedto decomposition it emits toxic vapors of NOx.

Purification Methods

It crystallises from water, *benzene/pet ether, ethyl acetate and sublimes in vacuo at 70o. Also purify it by dissolving in 0.1M H2SO4 and twice precipitating by addition of 1M NaOH to pH 8. Then recrystallise it from EtOH. For the dihydrochloride see Viologen below. [Collman et al. J Am Chem Soc 109 4606 1987, Beilstein 23 H 800, 23 III/IV 1371, 23/8 V 28.]
