The electrochemical generation of aryldiazonium salts from nitroarenes in a two-phase system (ethyl acetate/water) was reported for the first time. Some compounds including azo, azosulfone, and arylazides were prepared in good yields with good purity. Cathodically generated aryldiazoniums and anodically produced copper(Ι) ions were used to perform Sandmeyer reactions. To improve the method, an H-type self-driving cell equipped with a Zn rod as an anode was introduced and used for two-phase aryldiazonium production.

The copper-catalyzed cyanation of disulfides by azobisisobutyronitrile (AIBN) was developed, leading to thiocyanates in moderate to good yields. This procedure tolerates a series of functional groups, such as chloro, nitro, methyl and methoxycarbonyl in the phenyl ring of disulfides. Notably, it enables the use of two ArS units in (ArS)2. CuI was found to be essential for the in situ formation of cyanide anions. This journal is
Aromatic Thiocyanation using Supported Copper(I) Thiocyanate
Clark, James H.,Jones, Craig W.,Duke, Catherine V. A.,Miller, Jack M.
, p. 81 - 82 (2007/10/02)
Charcoal Supported copper(I) thiocyanate can be used to convert bromo- and iodo-benzenes into phenyl thiocyanates with no contamination from phenyl isothiocyanates.
