Transformations of hydrocarbons under metallic neodymium effect in conditions of mechanical activation at room temperature

The conversions of cyclohexene and 1.3- and 1.4-cyclohexadienes with metallic neodymium under the conditions of mechanical activation in a ball-mill at room temperature have been studied. Cyclohexane and polymer proved to be the final products of the cyclohexene conversion. Cyclohexadienes underwent a complicated conversion including isomerization, disproportionation and polymerization. A possible mechanism of all these transformations is proposed taking into account the participation of organometallic intermediates. 8 refs.; 3 tabs
