Param agnetic Interm ediates in Oxidative Coupling Reactions o f Tertiary Arom atic Am ines in Liquid Sulphur Dioxide
نویسنده
چکیده
R esults are presented which complement earlier studies on oxidative coupling pro cesses in arom atic amines and dem onstrate strikingly the ease w ith which such reactions take place in liquid sulphur dioxide. Further, yields and stability of the interm ediate cation radicals in this solvent compared with others of similar dielectric constant implies the participation of ionising forces not directly connected w ith dielectric properties. I t is suggested th a t liquid S 0 2 m ay prove a very useful solvent in which to study radical in term ediates of m any oxidation reactions.

Formation of Radical Intermediates in Sulphur Dioxide Solutions of Tertiary Aliphatic Amines
The addition of molecular iodine to solutions of te rtiary aliphatic amines in liquid sulphur dioxide is found to result in the formation of stable free radical oxidation in te r mediates. In triethylam ine solutions, oxidised under these conditions, arom atisation appears to take place to produce a pyridinyl radical. Radicals formed from N-ethyldim ethylam ine, N ,N -diethylm ethylam ine and ...
