A direct electroreductivedimerization of electron-deficient vinylarenes for the synthesis of 1,4-diarylbutane has been developed using a simple undivided cell with inexpensive carbonelectrodes at room temperature. The control and deuterium-labeling experiments of electroreductivedimerization suggest that the hydrogen source comes from the solvent CH3CN. This protocol provides a mild and efficient

Several dimethylphosphine sulfide- and phosphine-containing compounds have been discovered that chelate copper(I) with high affinity. In certain embodiments, the compounds can be used to quantify copper(I) in complex biological systems. In another embodiment, the compounds can be used for the treatment of copper(I)-related illnesses and conditions. In still other embodiments, the compounds are ratiometric probes.

Electrochemical nickel-catalyzed syntheses of triphenylenes by a) reductive trimerization of ortho-dibromobenzenes or ortho-bromoarylsulfurofluoridates, or b) reductive cross-coupling of ortho-dibromobenzenes to 2,2’-diiodobiphenyls, are described. The former provides a practical means for the construction of triphenylene derivatives in up to 87% isolated yield at room temperature. For 1,2-dihalo-3-methylbenzenes
