SN2 at nitrogen: The reaction of N-(4-cyanophenyl)-O-diphenylphosphinoylhydroxylamine with N.Methylaniline. A model for the reactions of ultimate carcinogens of aromatic amines with (bio) nucleophiles
The model reaction of 5 with 6 to give 7 and 8 (t-90%) follows the SN2 mechanism. From this result and from product studies it is concluded that the reactions of the ultimate carcinogen 1 with 6 and deoxyguanosine (dG) (and hence d other ultimate carcinogens of aromatic amines with bionucleophiles) follow the same mechanism.
5与6生成7和8(t-90%)的模型反应遵循S N 2机理。从该结果和产品研究得出的结论是,最终致癌物1与6和脱氧鸟苷(dG)(以及其他d最终的芳香胺与生物亲核剂)的反应遵循相同的机理。
