The ethylthio alkane ligands i.e. di(ethylthio)ethane, I, and di(ethylthio)propane, II, have been used for the synthesis of Pd(II) complexes. These complexes were covalently anchored to the modified MCM-41 matrix as supported hybrid catalysts (MCM-41/I as Pd–I and MCM-41/II asPd–II). Remarkable catalytic effects were observed when these supported catalysts act in n-hexane and n-heptane reformation reactions in the presence of H2. Catalyst Pd–I provided the high TONs of 2325 with 91% selectivity for n-hexane and high TONs of 2145 with 88% selectivity for n-heptane under optimized and relatively mild conditions. A carbenium-based mechanism has been included to explain the product formation. TGA analysis indicates that these catalysts were thermally stable up to the reaction temperature and recyclable for further utilization.
