Reductions by Electrochemically Generated Low-Valent Metal Salts and Base Metals

1 Reductions by Electrochemically Generated Low-Valent Metal Salts and Base Metals 

Low-valent metal ions take Ti , V , Sn , and Cr are common reducing agents with a wide applicability in organic synthesis Their use in stoichiometric 

The reductive cleavage of hydroxylamine and its derivatives by electro-generated TP and V forming aminyl radicals and the hydroxide ions has been studied intensively. The aminyl radicals are preferably trapped with alkenes and aromatic compounds. Thus, the reaction of hydroxylamine with electro-generated Tp in the presence of maleic acid yields aspartic acid (Eqs. (66)—(69)) 

12 3-phenyl- 3-hydroxy- CrClj or Cr(ClO )2 3-phenyl-propyne phenylallene my == 20-70 ex-cell 219) 

In the presence of 1,3-butadiene, diamino octodienes and dodecatrienes are formed Amination of aromatic compounds has been mentioned above (Sect. 3.3.3) Sensitive substituted hydroxylamines may be reduced to the amines in oxylic acid using electro-generated titanium(III)
