The mechanism of formation of the exocyclic dimeric π-enyl complex (C8H13PdCl)2 by reaction of 1,3-dimethylenecyclohexane, C8H12 with trans-PdCl2(C6H5CN)2 is discussed. Through UV, 1H NMR (90 MHz, 360 MHz) and 13C spectroscopic studies it was possible to show that the dimer is formed by the disproportionate of C8H12 to C8H14 and m-xylene, and further that it consists of diastereomeric products. The reaction of (-) R-3-methyl-1-methylencyclohexane, C8H14, with the Pd-salt confirms that during
