[reaction: see text] The synthesis of a molecularwire bearing an anthraquinone core and thioacetyl end groups for gold electrode binding is described. A model anthraquinone system, substituted with tert-butylthio groups, can be reversibly switched electrochemically from cross conjugated (low conductance "off") to linear conjugated (high conductance "on") via two-electron reduction/oxidation reactions

molecular wires, alkynemetathesis was investigated as an alternative to palladium-catalyzed coupling reactions for the synthesis of alkynyl ferrocenes. With a Mortreux catalyst system [Mo(CO)6, 4-chloro- or 2-fluorophenol], (1-propynyl)ferrocenes gave the expected homo metathesis products in moderate yields. Because the Mortreux catalyst system is not compatible with 1,1′-dialkynylferrocenes, a nitridomolybdenum
Simple and readily accessible aryl bromides are useful building blocks for thiol end-capped molecular wires. Thus, 4-bromophenyl tert-butyl sulfide and 1-bromo-4-(methoxymethyl)benzene serve as precursors for a variety of oligo(phenylenevinylene) and oligo(phenyleneethynylene) wires via efficient synthetic transformations as presented in this paper.
