Liquid–Liquid Interfacial Electron Transfer from Ferrocene to Gold(III): An Ultrasimple and Ultrafast Gold Nanoparticle Synthesis in Water under Ambient Conditions
Ferrocene
(Fc) in ether reduces HAuCl<sub>4</sub> in water within seconds under
ambient conditions in air upon stirring, forming ferricinium chloride
stabilized water-soluble 20 nm gold nanoparticles (AuNPs) that are
redispersible in the presence of poly(<i>N</i>-vinylmethylpyrrolidone)
or NaBH<sub>4</sub> + thiol. After reduction with NaBH<sub>4</sub> yielding Fc and 26 nm sodium poly(hydroxyborate) stabilized AuNPs,
the core size no longer changes following reactions with thiols providing
(RS)<sub><i>n</i></sub>AuNPs
