Abstract: A solid-supported Pd catalyst is suitable for C—C bond formation, e.g., via Suzuki-Miyaura and Mizoroki-Heck cross-coupling reactions, with a support that is reusable, cost-efficient, regioselective, and naturally available. Such catalysts may contain Pd nanoparticles on jute plant sticks (GS), i.e., Pd@GS, and may be formed by reducing, e.g., K2PdCl4 with NaBH4 in water, and then used this as a “dip catalyst.” The dip catalyst can catalyze Suzuki-Miyaura and Mizoroki-Heck cross coupling-reactions in water. The catalysts may have a homogeneous distribution of Pd nanoparticles with average dimensions, e.g., within a range of 7 to 10 nm on the solid support. Suzuki-Miyaura cross-coupling reactions may achieve conversions of, e.g., 97% with TOFs around 4692 h−1, Mizoroki-Heck reactions with conversions of, e.g., a 98% and TOFs of 237 h−1, while the same catalyst sample may be used for 7 consecutive cycles, i.e., without addition of any fresh catalyst.
