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.

A simple Pd/SiO2 catalyst which was modified with the ionic liquid [BMPL][DCA] gave an excellent yield of 88% towards cis-2-hexene in the stereoselective hydrogenation of 2-hexyne. The catalyst outperforms, even at full conversion, the commonly used lead-poisoned, toxic Lindlar catalyst
