, p. 5299 - 5302 (2000)
The novel benziodazole oxides (3) can be prepared by oxidation of the readily available 2-iodobenzamides (5 or 6) with potassium bromate. Benziodazole oxides can find practical application as selective oxidizing reagents analogous to the widely used Dess-
Rate constants for 1,n-hydrogen transfer reactions in some amino acid derived radicals

Absolute rate constants for 1,n-hydrogen atom transfers in some substituted amino acid derived radicals have been determined in benzene through the use of competitive kinetic experiments. Radicals derived from methyl N-(2-iodobenzoyl)-N-(tert-butyloxycarbonyl)glycinate, -alaninate, -leucinate, -tert-leucinate and -phenylglycinate undergo intramolecular 1,5-hydrogen atom transfer to afford the corresponding α-amino acid ester radicals with rate constants in the range: 1.0-4.3 × 107 s-1 at 80 °C. Where abstractable hydrogen atoms exist in the amino acid side-chain, 1,6- and 1,7-translocations are competitive processes.
