Self-assembled multilayer iron(0) nanoparticles (NPs, 6–10 nm), namely, sulfur-modified Au-supported Fe(0) [SAFe(0)], were developed for ligand-free one-pot carbon–carbon/carbon–nitrogen bond-forming reactions. SAFe(0) was successfully prepared using a well-established metal–nanoparticle catalyst preparative protocol by simultaneous in situ metal NP and nanospace organization (PSSO) with 1,4-bis­(trimethylsilyl)-1,4-dihydropyrazine (Si-DHP) as a strong reducing agent. SAFe(0) was easy to handle in air and could be recycled with a low iron-leaching rate in reaction cycles.

We have developed a continuous microwave irradiation-assisted Buchwald¬–Hartwig amination using our original Pd nanoparticle catalyst with copper plate as a co-existing metal solid. In this methodology, a microwave-controlled chemoselectivity was...

A co-existing solid, Al foil, plays a key role in ligand-free Suzuki–Miyaura coupling using SGlPd (sulfur-modified glass-supported Pd) and continuous microwave irradiation.

We report a carbon(sp2)‐carbon(sp3) bond‐forming cross‐coupling reactions by employing a nano‐size nickel catalyst supported on sulfur‐modified gold (SANi). This transformation demonstrates an efficient synthesis of functionalized aryl compounds, including heterocycles. Notably, the reactions proceeded in good yields with significantly low leaching of nickel from SANi. Moreover, SANi could be recycled several times without significant loss of catalytic activity.
