    Abstract: 1417338 Electrophilic substitution of nitrosamines BADISCHE ANILIN- & SODAFABRIK AG 13 April 1973 [15 April 1972 22 Sept 1972] 17818/73 Heading C2C Electrophilic substitution of a nitrosamine on the carbon atom α to the amino nitrogen is achieved by metallizing in the α position the nitrosamine of a secondary amine which bears at least one hydrogen atom in this position, and reacting the metallized product with an electrophite. In the nitrosamine R 1 R 2 N.NO, R 1 and R 2 may for example be alkyl, cyclohexyl, phenyl or benzyl, or the amino nitrogen may be part of a heterocyclic ring. The metallizing metal may be an alkali or alkaline earth metal or zinc, cadmium or monovalent copper, and organometallic compounds may be used as metallizing agent; lithium diisopropylamide is the preferred agent. Suitable electrophiles include carbonyl compounds, alkylating agents, e.g. alkyl or substituted alkyl halides, sulphates and sulphonates, acylating agent (carboxylic acid chlorides, esters, anhydrides, alkali metal salts, amides, nitriles, isocyanates, ketene and carbon dioxide); halohydrins obtained when using haloketones may react further by elimination of hydrogen halide to give epoxide; when using acyl halide, the resultant carbonyl compound may react with a further nitrosamine compound (e.g. PhCOCl with (CH 3 ) 2 N.NO gives PhCOR and/or PhC(OH)(R) 2 where R is CH 3 N(NO)CH 2 -). Inorganic electrophiles may also be used; use of iodine results in oxidative coupling of two nitrosamine molecules (e.g. RN(NO)CH 3 gives (RN(NO)CH 2 -) 2 where R is alkyl or aryl). Products may be reduced to hydrazines, or denitrosated to amines; products obtained when using carbonyl compounds contain hydroxy groups and may be dehydrated (e.g. benzaldehyde + dimethyl nitrosamine # PhCH(OH)- CH 2 N(NO)CH 3 # PhCH=CH-N(NO)CH 3 ).
