Carbohydrate derived thiosemicarbazone and semicarbazone palladium complexes: homogeneous catalyst for C–C cross coupling reactions

Palladium complexes of carbohydrate derived thiosemicarbazone and semicarbazone were used as catalysts for Suzuki and Sonogashira cross coupling reactions at ambient temperature. The catalysts were active after 5 cycles. Activation of 4-chlorotoluene has been achieved with 0.1% catalyst loading at ambient temperature with TON of 970 in 4 h.
