The Grignard reagent is both a strong base and a strong nucleophile. As a base it will react with all protons that are
solution-phase reaction of Au nanoparticles with organic dithiols leading to the self-assembly of cross-linked nanonetworked with nanometallic electronic conductivity has been reported in a previous communication. Bard and co-workers have extended this method for the fabrication of self- assembled spherical ultramicroelectrodes by confining the self-assembly process to the tip end of a quartz mic
