2-HEXYNE Usage And Synthesis

Chemical Properties

clear light yellow liquid

General Description

Pd/SiO₂ modified with ionic liquid catalyzed lead free stereoselective hydrogenation of 2-hexyne has been reported. Polymerization of 2-hexyne in toluene catalyzed by MoCl₅.Ph₄Sn and WCl₆.Ph₄Sn has been reported. Mechanism of hydrogenation of 2-hexyne in solution on selective and unselective bulk Pd has been investigated. Lanthanum-catalyzed dimerization of 2-hexyne has been reported.

Purification Methods

Purify as for 1-hexyne above. [Beilstein 1 IV 1009.]
