Description and Uses

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.
