A kinetic and product study has been carried out for the reactions of silylamines 1a and 1b with O-1(2) in MeCN and (80:20) MeCN-MeOH. Indications suggesting an electron-transfer step following exciplex (1) formation have been obtained. However, the fate of the radical cation is solvent dependent. The radical cation undergoes desilylation in MeCN-MeOH and deprotonation in MeCN.

Abstract
A kinetic and product study has been carried out for the reactions of silylamines 1a and 1b with O-1(2) in MeCN and (80:20) MeCN-MeOH. Indications suggesting an electron-transfer step following exciplex (1) formation have been obtained. However, the fate of the radical cation is solvent dependent. The radical cation undergoes desilylation in MeCN-MeOH and deprotonation in MeCN.File allegati a questo prodotto
