Quinoxaline Chemical Properties,Usage,Production

Chemical Properties

light yellow to brown crystalline

Uses

Quinoxaline is a reagent used in the synthesis of quinoxaline diimides as small molecule non-fullerene acceptors for organic solar cells.

Uses

Organic synthesis.

Definition

ChEBI: A naphthyridine in which the nitrogens are at positions 1 and 4.

Synthesis Reference(s)

Journal of the American Chemical Society, 69, p. 795, 1947 DOI: 10.1021/ja01196a015
The Journal of Organic Chemistry, 55, p. 1744, 1990 DOI: 10.1021/jo00293a014
Organic Syntheses, Coll. Vol. 4, p. 824, 1963

General Description

Transition metal-free acylation of quinoxaline derivatives, by cross dehydrogenative coupling (CDC) reaction, were studied.

Purification Methods

Crystallise quinoxaline from pet ether. It crystallises as the monohydrate on addition of water to a pet ether solution. It has UV: at 242 and 331nm (Ho –2); 234 and 316nm (pH 7.1). The picrate has m 161-162o.[Albert & Phillips J Chem Soc 1294 1956, Beilstein 23 H 176, 23 II 177, 23 III/IV 1226, 23/7 V 135.]
