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.]
