Electrosynthesis metal halides

The electroreductive carbonylation and carboxylation of organic halides catalyzed by different metal complexes is summarized in Section 9.10.5. Electrogenerated Ni° complexes containing bpy193-196 or pentamethyldiethylenetriamine196-199 ligands are effective catalysts for the electrosynthesis of... 

The synthesis of metalloporphyrins which contain a metal-carbon a-bond can be accomplished by a number of different methods(l,2). One common synthetic method involves reaction of a Grignardreagent or alkyl(aryl) lithium with (P)MX or (PMX)2 where P is the dianion of a porphyrin macrocycle and X is a halide or pseudohalide. Another common synthetic technique involves reaction of a chemically or electrochemically generated low valent metalloporphyrin with an alkyl or aryl halide. This latter technique is similar to methods described in this paper for electrosynthesis of cobalt and rhodium a-bonded complexes. However, the prevailing mechanisms and the chemical reactions... 

Very few transition-metal catalyzed electroreductive carbon-heteroatom bond formations have been described. The electrochemical silylation of allylic acetates was carried out in the presence of Pd-PPha [131]. The electrosynthesis of arylthioethers from thiophenol and aryl halides [132] and the coupling of bromobenzene with dichlorophenylphosphine [133] were performed with Ni-bpy as catalyst. 

Iron was among the metals, used in the electrosynthesis of a wide range of alcohols from organic halides and ketones or aldehydes (see Sect. 2.4 and 3.4...
