1-VINYLNAPHTHALENE Usage And Synthesis

Chemical Properties

Colourless to Pale Green Liquid

Uses

1-Vinylnaphthalene is used as a precursor of polynuclear aromatic hydrocarbons in tobacco smoke. It is also used as pharmaceutical intermediate.

Uses

1-Vinylnaphthalene may be used in the synthesis of 1-naphthyl-1,2-ethanediol, which can further be utilized as a metal hydrogenated catalyst. It may also be used as a substrate material to produce azidocyanation based products.

Definition

ChEBI: 1-vinylnaphthalene is a vinylnaphthalene.

Synthesis Reference(s)

Tetrahedron, 52, p. 915, 1996 DOI: 10.1016/0040-4020(95)00950-7

Purification Methods

Commercial material can contain up to 2% of poly-1-vinylnaphthalene. Fractionally distil it under reduced pressure using a spinning-band column, dry it with CaH2 and again distil it under vacuum. Store it in sealed ampoules in a freezer. It has max (cyclohexane) at 210 and 320nm. The picrate has m 105-106o. [Beilstein 5 H 585, 5 III 1773, 5 IV 1833.] It is an irritant.
