| Abstract: | reaction: see text] A kinetic and product study has been carried out for the reactions of silylamines 1a and 1b with (1)O(2) in MeCN and (80:20) MeCN-MeOH. Indications suggesting an electron-transfer step following exciplex (I) 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. |
