Rearrangement processes nitrenium ions

The application of the azide clock methodology to nitrenium ions was made by Fishbein and McClelland who showed that NJ trapped a reactive intermediate identified as the nitrenium ion 75m, during the Bamberger rearrangement of N-(2,6-dimethylphenyl)hydroxylamine (Scheme 33)7 Kinetic studies showed that the NJ-solvent partitioning occurred after the rate-limiting step of the reaction so an Sn2 process could be eliminated. The selectivity ratio, was determined to be 7.5 M . Assuming that k is... [Pg.197]
