Chen, Qian published the artcileCyclization or Hydrogen Migration: Theoretical Study and Experimental Evidence on the Reactivities of Unsaturated Amidyl Radicals, Recommanded Product: N-(tert-Butyl)-S-phenylthiohydroxylamine, the publication is Organic Letters (2005), 7(8), 1625-1627, database is CAplus and MEDLINE.
Theor. calculations (B3LYP/6-31G*) backed up by deuterated experiments reveal that the N-substituents (R) play a crucial role in determining the reaction pathways of unsaturated amidyl radicals. With the increase of the bulkiness of N-alkyl group, the activation energy for 6-exo cyclization increases steadily, while the activation energy for 1,5-H abstraction remains almost unchanged. Therefore, cyclization occurs exclusively when R is H while 1,5-H migration occurs exclusively when R is t-Bu.
Organic Letters published new progress about 19117-31-8. 19117-31-8 belongs to catalysis-chemistry, auxiliary class Oxidant, name is N-(tert-Butyl)-S-phenylthiohydroxylamine, and the molecular formula is C10H15NS, Recommanded Product: N-(tert-Butyl)-S-phenylthiohydroxylamine.
